ES = effect size = (M2-M1)/Sb, where M2 is the mean score at year 2, M1 is the mean score at baseline, and Sb is the standard deviation at baseline; SRH = self-rated health; SPPB = Short Physical Performance Battery; SEM = standard error of measurement = Sb*√(1-r), where Sb is the standard deviation at baseline and r is the test-retest reliability coefficient; MDC90 = minimal detectable change with 90% confidence = SEM*1.645*sqrt2.
