summary: Inclusion of suspected COVID-19 in 1 of 3 trials may introduce selection bias, but the impact appears limited.

classifier: Factor likely does not have potential to impact results (Scientific Evidence Code System (SEVCO) -- EXAMPLE VERSION for EBMonFHIR Implementation Guide#SEVCO:00209), Low risk of bias (Scientific Evidence Code System (SEVCO) -- EXAMPLE VERSION for EBMonFHIR Implementation Guide#SEVCO:00186)

summary: The study design used response-adaptive randomization in which group assignment ratios could be modified during the trial on the basis of response-adaptive interim analyses to favor the assignment of patients to the treatment group showing greater benefit. The confounding by time (imbalanced randomization with time period) is not adequately reported to determine the potential influence on results or adequacy of adjusted analyses.

summary: Awareness of treatment assignment may reduce clinical decision to initiate some types of "organ support" in patients with higher risk of major bleeding.

summary: The influence of awareness of treatment assignment by the treating clinicians on the initiation of organ support (which is the primary outcome) was already addressed as Performance Bias so is not repeated here as a bias in detecting the outcome.

summary: Only 19 of 1190 (1.6%) therapeutic group and 6 of 1054 (0.6%) prophylactic group were excluded after randomization.

summary: It is unknown if the results are sensitive to the analytic method, and the stopping criteria were based on statistical significance and not magnitude of effect.
