Readmission to hospital	14	0·80* (0·53–1·08)	<0·0001	94·74
Readmission to hospital (rates)†	2	0·75‡ (0·47–1·20)	0·2332	99·71

Treatment adherence	3	2·12* (1·69–2·55)	<0·0001	0

^*Standardised mean difference, random-effects model.

^†Two studies reported readmission data as rate ratios, which cannot be combined with other data formats, so are reported as a separate analysis.
