Red cell alloimmunization in multitransfused hepatobiliary patients at hospital Selayang.
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
backgroundTransfusion support is vital for the management of patients with hepatobiliary disease. Repeated blood transfusions increase the risk of alloimmunization, i.e., the development of alloantibodies, which might lead to difficulties in blood crossmatching.
aimsThis study aims to: (1) determine the incidence of red blood cell (RBC) alloimmunization and (2) evaluate the associations between antibody development and demographic factors among hepatobiliary patients.
methodABO blood grouping, antibody screening, antibody identification and crossmatch were done on all patients samples included in the study. SETTINGS AND
designA cross-sectional study was conducted from February 2021 to September 2021, with a total of 132 samples from hepatobiliary patients. The relationships between RBC alloimmunization in transfused hepatobiliary patients and demographic factors (gender, age, and history of transfusion) were assessed by binary logistic regression.
resultsOverall, 67.4% of the patients developed alloimmunization. The majority had a single alloantibody (75.2%) and the most frequently identified antibody specificities were anti-E (37.6%), anti-c (12.8%), anti-Mia (14.4%), and anti-Kidd (11.2%). The predominant antibodies were those against the Rh system (58.4%). Female patients recorded the highest incidence of alloimmunization (69.8%). Female patients also demonstrated a higher tendency to produce both anti-E + anti-c than male patients.
conclusionThe prevalence of RBC alloimmunization is high among hepatobiliary patients and it may cause complications requiring multiple transfusions. The number of transfused packed cells has been clearly shown to be proportionally significant with the risk for alloimmunization in hepatobiliary patients. Hence, this study highlights the importance of immunohematology tests before blood transfusion.
