There was no evidence of a significant association between the RR/HR and baseline risk of diabetes (regression coefficient 0.79; 95% CrI −0.22, 1.92), cardiovascular mortality (regression coefficient −0.16; 95% CrI −0.65, 0.35) and all-cause mortality (regression coefficient 0.12; 95% CrI −0.20, 0.38). Limiting the analysis to studies that controlled for physical activity as a covariate decreased the precision with which pooled RR/HRs were estimated but not enough to change overall conclusions (Table 2).
