FIGURE 4.

High platelet:red blood cell ratio has no effect on thromboembolic events or organ failure in trauma patients included in randomized controlled trials. Meta‐analyses of high and low platelet:RBC ratio on (A) thromboembolic events (TEE) and (B) multiple organ dysfunction syndrome (MODS) represented in a forest plot. Weighted mean platelet:RBC ratio in the high ratio group was 1.15 (SD 0.34) and in the low ratio group 0.56 (0.15) for TEE and 0.83 (0.56) and 0.39 (0.27) for MODS. Events = number of patients affected, total = total number of patients, high = group with highest platelet:RBC ratio, low = group with lowest platelet:RBC ratio, M‐H = Mantel–Haenszel
