Comparison of the eradication rate of PBMT as first-line therapy in intention-to-treat analysis. (A) 10-day/14-day PBMT versus 14-day TT; (B) 10-day/14-day PBMT versus 10-day SQT; and (C) 10-day/14-day PBMT versus 10-day CCT.

M-H, Mantel-Haenszel test; CI, confidence interval; PBMT, bismuth quadruple therapy; TT, standard triple therapy; SQT, sequential therapy; CCT, concomitant therapy. *Risk of bias: A, random sequence generation (selection bias); B, allocation concealment (selection bias); C, blinding of participants and personnel (performance bias); D, blinding of outcome assessment (detection bias); E, incomplete outcome data (attrition bias); F, selective reporting (reporting bias); G, other bias.
