Eligible studies included SRs, randomized controlled trials (RCTs), and matched cohort observational studies between 1946 and March 2025. Populations included were hypoproliferative thrombocytopenia, periprocedural prophylaxis, cardiovascular surgery, consumptive thrombocytopenia, and intracranial hemorrhage. The intervention was restrictive versus liberal platelet transfusion strategies on outcomes of mortality and bleeding. Duplicate screening and data extraction occurred.

The evidence quality varied. For hypoproliferative thrombocytopenia, 11 RCTs were analyzed, with 9 RCTs at moderate risk of bias (ROB). Two RCTs were identified for dengue, with high ROB for bleeding. One RCT was identified each in cardiovascular surgery, intracranial hemorrhage, and periprocedural prophylaxis. Meta\u2010analyses indicated no significant effect for outcomes of mortality or bleeding by strategy, but confidence intervals (CIs) were wide. Effect estimates were 1.32 [0.93, 1.86] for all\u2010cause mortality in hypoproliferative thrombocytopenia, 0.80 [0.38, 1.70] in cardiovascular surgery, and 0.69 [0.47, 1.03] in critically ill neonates or dengue patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>A consistent lack of benefit with liberal platelet transfusion was observed across analyzed populations, although wide confidence intervals do not exclude clinically meaningful impacts.
