Effect on outcome of compulsory community treatment compared with controls

	Number of studies	Effect size (95% CI)	p value	Heterogeneity (I2)
Readmission to hospital	17	−0·14* (−0·41 to 0·14)	0·3358	98·06
Readmission to hospital (rates)†	2	1·98‡ (0·78 to 5·01)	0·1509	94·11
Inpatient bed-days	11	0·13* (−0·08 to 0·34)	0·2335	97·18
Use of community services	9	0·38* (0·19 to 0·58)	0·0001	96·92
Treatment adherence	2	0·91* (−0·70 to 2·51)	0·2677	87·93

Control was no compulsory community treatment.

^*Standardised mean difference, random-effects model.

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