Twenty-four studies (18 prospective, 6 retrospective) with a total of 4,151 patients were included. The 60-day follow-up data were available for 2,547 patients and the 30-day follow-up for all patients.
Significant differences were found at 30 days of follow-up for: ASA versus low IVIG (95% CI: 0.080, 0.170, p<0.0001); low IVIG versus high IVIG (95% CI: 0.035, 0.105, p<0.0001); high IVIG versus single IVIG (95% CI: 0.053, 0.107, p<0.0001); but not for high IVIG and low ASA versus high IVIG and high ASA (95% CI: -0.007, 0.084, p=0.097).
Significant differences were found at 60 days of follow-up for: ASA versus low IVIG (95% CI: 0.017, 0.103, p=0.003); low IVIG versus high IVIG (95% CI: 0.038, 0.096, p<0.0001); but not for high IVIG versus single IVIG (95% CI: -0.003, 0.045, p=0.092); or high IVIG and low ASA versus high IVIG and high ASA (95% CI: 0.025, 0.041, p=0.319).
