Evaluating agreement between bodies of evidence from randomized controlled trials and cohort studies in medical research: a meta-epidemiological study

Table 5 Multivariable meta-regression for each PI/ECO-domain across body of evidence-pairs with binary outcomes within the category “similar but not identical”

PI/ECO	Estimate	95 % CI	P − value
Intercept	0.98	(0.74, 1.29)	0.8610
Population^a	1.14	(0.88, 1.49)	0.3177
Intervention/Exposure^a	0.89	(0.72, 1.11)	0.3060
Comparator^a	1.12	(0.91, 1.37)	0.2749
Outcome^a	1.02	(0.61, 1.72)	0.9361
Heterogeneity: τ² = 0.00, Q = 34.35, p − value = 1
