Hospital stay (after readmission)	2	803			−0.57	(−5.32 to 4.17)‡
Readmission per patient	3	1370			−0.12	(−0.24 to 0.01)‡
ED visit per patient	2	4342			−0.15	(−0.53 to 0.23)‡
Patients with ADE	3	1401	0.94	(0.75 to 1.20)‡

*RR is >1 when the intervention increased the number of patients who did not revisit the hospital (ie, it showed success).

†p<0.01.

‡p>0.05.

ADE, adverse drug event; ED, emergency department; RR, risk ratio; WMD, weighted mean difference.
