  Figure 2.. Forest plot of the incidence of in-hospital or 30-day mortality and a risk of bias summary for a door-in to door-out (DIDO) time of ≤30 min vs. >30 min. Risks of bias were categorized as follows: A, random sequence (selection bias); B, allocation concealment (selection bias; background factors of the 2 groups are unknown); C, performance bias (the intergroup difference in treatment strategy is unknown); D, detection bias (the primary outcome in the present analysis was only short-term mortality [low risk]); E, attrition bias (short-term prognosis with a high follow-up rate [low risk]); F, reporting bias (there seems to be no reporting bias because there are only 2 reports in this analysis [low risk]); G, other bias (not just reporting favorable outcomes [low risk]).
