Safety and efficacy of least incompatible red cell units in autoimmune hemolytic anemia: A prospective analysis of hemoglobin increment and hemolysis after transfusion.
Article in Asian journal of transfusion science. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundRed blood cell (RBC) transfusion is a challenge in autoimmune hemolytic anemia (AIHA) patients due to pan reactivity and crossmatch incompatibility. Apprehensions about the safety and efficacy of least incompatible (best-matched) red cells are common among treatment providers.
aimA primary objective was to study the effect of RBC transfusion on hemolysis parameters (hemoglobin [Hb], serum bilirubin, serum lactate dehydrogenase [LDH], and reticulocyte count) in AIHA patients. SETTINGS AND
designThis was a hospital-based prospective observational study conducted on 40 AIHA patients attending the department of internal medicine from January 2020 to July 2021 who received RBC Transfusions. METHODOLOGY: Blood samples were collected for evaluating hemolysis parameters: Hb, reticulocyte count, serum bilirubin, and serum LDH before transfusion and compared with the same parameters within 12 h after transfusion. STATISTICAL ANALYSIS: Analysis was done by SPSS software Version 16. Paired
resultsThe median age at presentation was 42 years with a female preponderance (67.5%). Majority of the patients belong to warm AIHA (73%) and Secondary AIHA (60%). Compatible RBC units could be provided to 57% of cases and 43% were transfused with the least incompatible units. The mean pretransfusion Hb in AIHA was 4.3 mg/dl and showed a statistically significant increase after transfusion (
conclusionRBC transfusions in AIHA patients provide Hb increment similar to other anemic patients. RBC transfusions should not be denied in AIHA patients in view of hemolysis and best-matched units also may be transfused in indicated cases.
