The relationship between perceived and measured frailty was assessed using percent agreement, kappa statistic, Pearson's correlation coefficient, and prevalence of misclassification of frailty.
OR: Odds Ratio by exposure unit 95%CI: 95% Confidence Intervals p: p-value of a test of a zero coefficient P: Prevalence of pleural plaques.
OR: Odds Ratio by exposure unit 95%CI: 95% Confidence Intervals p: p-value of a test of a zero coefficient P: Prevalence of asbestosis TSFE: Time Since First Exposure.
A linear trend was calculated using Pearson correlation coefficient for prevalence ratios of children aged 0 12 months and older than 12 months requiring PC in the respective years of the study.
A significant correlation coefficient between the prevalence of antibodies to toxoplasma and dryness during late summer was reported.
All the weights are calculated by aggregating the results from a number of pairwise comparison square matrices, where the elements aij of a matrix (also called "dominance coefficients") represent the prevalence of criterion Ai on criterion Aj in reference to the corresponding macro-criterion/goal.
The regression coefficients for retinopathy prevalence were 1.1 (P = 0.079) and 4.3 (P < 0.001) for before and after the change point, respectively.
The linear regression coefficients of retinopathy prevalence by the FPG 1% increment approach were 0.8 (P = 0.476) and 3.9 (P < 0.001) for before and after the change point of 5.8 mmol/l, respectively.
Finally, in an exploratory analysis, we estimated, at the ecological level, the associations (Pearson's correlation coefficients) between the prevalence of health service use and the proportion of consultations requiring out-of-pocket expenses, health insurance coverage, and pension coverage.
