Retrieval of Individual Participant Data for Exercise Meta-Analyses May Not Be Worth the Time and Effort

Table 1

Results for exact logistic regression for receipt of IPD ().

Variable	OR	SE		95% CI
Year	1.05	0.09	0.58	0.90, 1.27
Country	1.36	1.12	1.00	0.20, 10.90

Note: IPD, individual participant data; OR, odds ratio; SE, standard error; , alpha value, calculated as 2 the probability of the sufficiency statistic, a statistic derived from single-parameter tests of the null hypothesis that the coefficient equals zero versus a 2-sided alternative; 95% CI, 95% confidence interval; alpha () and 95% CI calculated from exact conditional distributions; both independent variables (year and country) calculated separately with the other variable conditioned out of the calculation.
