3.4.2. Patient-related factors

We conducted a meta-analysis of patient related factors, including male sex (15 studies [3, 6-8, 13-23] ),
smoking (3 studies [14, 17, 19] ), drinking (2 studies [17, 19] ), hypertension (11 studies [3, 6, 8, 13-15, 17-19, 21,
22] ), diabetes (11 studies [3, 6, 8, 13-15, 17-19, 21, 22] ), cardiovascular disease (9 studies [6, 8, 13-15, 17, 19, 21,
22] ), cerebrovascular disease (4 studies [6, 8, 15, 22] ), antithrombotic drugs (7 studies [3, 6, 7, 15, 18, 19, 21] ),

aspirin (3 studies [13, 19, 21] ), clopidogrel (2 studies [13, 17] ), warfarin (2 studies [13, 17] ). The results
showed that male sex (RR=1.56, 95% CI: 1.34-1.81, P<0.05), hypertension (RR=1.27, 95% CI:
1.09-1.47, P<0.05), cardiovascular disease (RR=1.56, 95% CI: 1.23-1.97, P<0.05), antithrombotic

drugs (RR=1.96, 95% CI: 1.24-3.09, P<0.05), aspirin (RR=1.50, 95% CI: 1.06-2.11, P<0.05), and
clopidogrel (RR=1.89, 95% CI: 1.03-3.45, P<0.05) (Fig.S1-6) were associated with increased risk
of DPPB. Smoking (RR=1.36, 95% CI: 0.50-3.66, P>0.05), drinking (RR=0.82, 95% CI: 0.47-1.42,
P>0.05), diabetes (RR=1.00, 95% CI: 0.71-1.39, P>0.05), cerebrovascular disease (RR=1.19, 95%
CI: 0.83-1.70, P>0.05), and warfarin (RR=2.70, 95% CI: 0.57-12.68, P>0.05) (Fig. S7-11) were not

related to the occurrence of DPPB (see Table 2).
3.4.3. Polyp-related factors
A meta-analysis of polyp-related factors was performed, including polyp number > 3 (2 studies [13,

18] ), polyp number ≥ 3 (2 studies [3, 6] ), polyp size ≥10 mm (3 studies [3, 8, 22] ), polyp morphology
(3 studies [3, 19, 22] ), polyp location (8 studies [3, 7, 8, 13, 16, 19, 20, 22] ), and polyp pathological type:, i.e.,
adenomas (7 studies [3, 7, 8, 16, 19, 20, 22] ), non-adenomas (2 studies [3, 7] ), serrated polyp (3 studies [7,
19, 20] ), proliferative polyp (4 studies [7, 8, 19, 20] ), malignancies (5 studies [8, 16, 19, 20, 22] ). The results

showed that the number of polyps > 3 (RR=1.44, 95% CI: 1.12-1.85, P < 0.05), polyp size ≥ 10 mm
(RR=3.57, 95% CI: 2.58-4.95, P < 0.05), pedunculated polyps (RR=4.32, 95% CI: 2.97-6.30, P <
0.05) and malignancies (RR=2.66, 95% CI: 1.49-4.75, P < 0.05) (Fig. S12-15) were associated with
