Moment Correlation Coefficient (moment + correlation_coefficient)
Kinds of Moment Correlation Coefficient Selected AbstractsCytomegalovirus and cyclosporin-induced gingival overgrowth in children with liver graftsINTERNATIONAL JOURNAL OF PAEDIATRIC DENTISTRY, Issue 4 2002M.-T. Hosey Summary., Objective. To determine whether cytomegalovirus (CMV) is associated with gingival overgrowth in paediatric liver graft recipients treated with cyclosporin. Study design. Thirty-four children, 25 of whom were under 5 years of age, who had undergone liver transplantation, were examined. An Index of Severity of Gingival Overgrowth was used to measure the prevalence and severity of the gingival overgrowth. The trough cyclosporin level was recorded and the CMV status of the patient matched to the dental findings. The association between the severity of gingival overgrowth and CMV infection was examined using the contingency coefficient. An anova was used to assess the association between the circulating trough cyclosporin concentration and the severity of gingival overgrowth. Pearson's Product Moment Correlation Coefficient was used to examine the association between the duration of exposure to cyclosporin and the severity of gingival overgrowth. Results. There was a significant inverse association between the duration of exposure to cyclosporin and the severity of gingival overgrowth. There was no relationship between the trough cyclosporin concentration and the severity of gingival overgrowth. There was no association between CMV and gingival overgrowth. Conclusion. Gingival overgrowth was related to the duration of cyclosporin therapy but was neither more prevalent nor more severe in subjects who were CMV seropositive. [source] Prevalence of incontinence and incontinence-specific quality of life impairment in women with cystic fibrosis,,NEUROUROLOGY AND URODYNAMICS, Issue 8 2009M. Vella Abstract Aims Cystic fibrosis (CF) is the commonest autosomal recessive disorder in Caucasians. With advancing medical technology, the life expectancy has more than double in the last twenty years. This has led to new unforeseen health problems like urinary incontinence. The aim was to establish the prevalence, symptomatic typology, and quality of life impact of incontinence in a population of women with CF. Methods Women were recruited from two London tertiary referral centres for CF. They were asked to fill in a self- completed anonymous King's Health Questionnaire (KHQ) for assessment of symptoms and quality of life Impairment. Their age was also noted. Descriptive statistics are reported. Correlation was assessed using Pearson's Product Moment Correlation Coefficient (r). Results One hundred and forty six women were approached for enrolment. 98(67%) consented to take part in study. Their mean age was 28. Seventy three (74%) reported symptoms of urinary incontinence, which in all cases was perceived as stress urinary incontinence. Of these 44(60%) reported mild stress incontinence, 16(22%) moderate stress incontinence and 13(18%) severe stress incontinence. Continent and incontinent women perceived their general health to be similarly poor (mean score 40 vs 44 points). Strong positive correiations were found between age and stress urinary incontinence severity (r=0.742; P <0.001) and between age and total King's Health Questionnaire score (r=0.828; P <0.001). Conclusions Women with CF have a higher prevalence of stress urinary incontinence than the general population, with both the prevalence and associated quality of life impairment increasing with age.

[source] Correlation between the Individual and the Combined Width of the Six Maxillary Anterior TeethJOURNAL OF ESTHETIC AND RESTORATIVE DENTISTRY, Issue 3 2009LUIZ CARLOS GONÇALVES DMD ABSTRACT Purpose:, There is a consensus in the community of dental research that the selection of undersized artificial maxillary anterior teeth offers an unnatural appearance to the denture. Several methods to select the adequate width of these teeth are of questionable validity, and many dentures have an obviously artificial appearance. This article assessed the relationship between the individual and the combined width of maxillary anterior teeth. Materials and Methods:, Impressions were made of the anterior dentition of 69 dentate undergraduate students with rubber impression silicon, and casts were formed. The individual widths of the maxillary anterior teeth were measured by using a digital caliper (SC-6 digital caliper, Mitutoyo Corporation, Tokyo, Japan), and the combined width was registered by both adding the individual width and using a flexible millimeter ruler. Results:, Student's t -test showed significant differences between the analogous teeth and different sides of the maxillary dental arch (p = 0.001), with the exception of the central incisor (p = 0.984). Pearson's product moment correlation coefficient showed significant positive correlation between all the measurements compared (p = 0.000). Linear regression analysis concluded three mathematical equations to obtain the individual tooth width after measuring the combined width of the six maxillary anterior teeth by using a flexible millimeter ruler. Conclusions:, The individual tooth width can be determined if the combined width of the maxillary anterior teeth is obtained by using a flexible millimeter ruler. CLINICAL SIGNIFICANCE The adequate selection of each maxillary anterior tooth width can offer variance and individuality to the denture, particularly for partially dentate patients. By offering an adequate tooth-to-tooth relationship, the esthetic result of the oral rehabilitation treatment can be improved. [source] Anxiety and pain experience of patients undergoing intra-oral buccal mucosa biopsyORAL SURGERY, Issue 3 2009C.S. Barrett Abstract Aim:, The aim of this study was to investigate anxiety levels, expected pain and actual pain experienced by patients undergoing intra-oral biopsy. Materials and methods:, Forty-four patients who required a single site, buccal mucosa biopsy under local anaesthesia as their first ever oral biopsy were recruited. Data were collected immediately before and after their biopsy procedure. This included demographic information, state and trait sections of Spielberger's State Trait Anxiety Inventory and 100 mm visual analogue scales for expected pain and actual pain. Data were analysed using paired t -tests, independent t -tests and Pearson's product moment correlation coefficient. Results and conclusions:, Patients were anxious pre-operatively (mean s-anxiety 42.02), which was a highly statistically significant rise above baseline (P < 0.001). Patients expected (40.4) significantly (P < 0.001) higher pain from the procedure than they actually experienced (4.5). There were some indicators that women and patients with high trait anxiety were more likely to be anxious pre-operatively. [source] Correlates of apparel significance among older men and womenINTERNATIONAL JOURNAL OF CONSUMER STUDIES, Issue 3 2000Usha Chowdhary Abstract A total of 978 older men and women (over 65 years) were systematically identified from a list of registered voters and asked to participate in a study examining the correlates of apparel significance (extent to which apparel is considered important by an individual). A postal survey technique was used to collect the data. Both descriptive and inferential statistics were used to analyse and interpret the data. The condition number index was used to test for multicollinearity of data. Pearson product moment correlation coefficients, analysis of variance and stepwise multiple regression were used to analyse the data. The findings revealed that apparel significance was positively related to self-esteem, age perception, media usage, opinion leadership and social participation. Stepwise multiple regression results indicated that 65·3% of the variance was explained by media usage, opinion leadership and sex. [source] | ||||||||||
