The role of prophylactic transfusion on the maternal and fetal outcomes in pregnant women with sickle cell disease: A systematic review and meta-analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn the present review, we aimed to synthesize evidence from studies on the safety and effectiveness of prophylactic blood transfusion in pregnant women with sickle cell disease. MATERIAL AND
methodsTo gather relevant information, we conducted systematic electronic searches of databases such as SCOPUS, Medline via PubMed, Web of Science, and Cochrane Central Register of Controlled Trials. We included both retrospective and prospective studies that examined the impact of prophylactic blood transfusions during pregnancy. The collected data were analyzed using Review Manager, version 5.3.
resultsThe review included 15 cohort studies. The overall findings indicated a preference for the prophylactic blood transfusion group over the control group across several key parameters. Specifically, the prophylactic group demonstrated lower rates of maternal mortality (odds ratio [OR] = 0.33; 95% confidence interval [CI] = 0.10-1.13; P = .08), reduced incidence of vaso-occlusive painful events (OR = 0.31; 95% CI = 0.14-0.73; P = .007), fewer pulmonary complications (OR = 0.21; 95% CI = 0.08-0.53; P = .001), decreased perinatal mortality (OR = 0.35; 95% CI = 0.17-0.75; P = .03), and lower likelihood of preterm birth (OR = 0.67; 95% CI = 0.47-0.96; P = .02). Notably, statistically significant heterogeneities were observed in the pooled effect estimates.
conclusionThe present meta-analysis indicated that prophylactic blood transfusion in pregnant women with sickle cell disease may improve maternal and fetal outcomes. However, substantial variations in the methodology and transfusion protocols among the included studies limited the credibility of the current evidence supporting the routine clinical use of prophylactic transfusion for SCD during pregnancy.
