Table 2 Fixed-effects meta-analysis results for clinically relevant delayed bleeding

Antiplatelet agent subgroup	No. of enrolled studies	No. of events due to DB (deaths or neurosurgery)	No. of patients at risk	CRDB mean estimated risk (95% CI)
All	16	5	2930	0.17% (0.06–0.40%)
ASA	11	3	1706	0.18% (0.04–0.51%)
Clopidogrel	9	0	265	0.00% (0.00–1.38%)
DAPT	6	0	175	0.00% (0.00–2.09%)

CRDB = clinically relevant delayed bleeding as defined in the text; 95% CI = 95% confidence interval; All = all patients included in the analysis; ASA = acetylsalicylic acid; DAPT = dual antiplatelet therapy
