Among the included studies, three (1, 2, and 5) were randomized clinical trials,
while two (3 and 4) were retrospective. The overall risk of bias, evaluated using
RoB 2, was deemed low for studies 1 and 2, with some concern identified for
study 5. Assessment with ROBINS-I revealed a serious and moderate overall risk
of bias for studies 3 and 4, respectively (Tables 2 and 3).
