Hemolysin test as a tool to screen high-titer Group O platelet apheresis donors: A prospective study.

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
backgroundMinor ABO-incompatible apheresis platelet transfusion poses a risk of hemolytic transfusion reactions in non-Group O recipients when donor's plasma possesses unusual high titers for anti-A and anti-B. The aim was to determine whether the hemolysin test can be used as a screening tool to predict high-titer Group O platelet apheresis donors.
methodsA prospective study, with Group O platelet donor's samples, was tested for hemolysin test and antibody titration test in parallel. Antibody titration was also performed on products suspended in platelet additive solution (PAS). Hemolysin test was assessed for diagnostic accuracy against antibody titration. Chi-square test and Mann-Whitney
resultsAmong 107 Group O platelet donations, median anti-A and anti-B titers in donors were 32 (8-128) and 32 (4-256), respectively. High titer (≥128) for ABO antibodies was seen in 18% of donations, whereas hemolysin test was positive in 69% of donations. Hemolysin test results differ significantly with antibody titration results (
conclusionAdopting hemolysin test as a screening tool may label a large number of units (69%) unsuitable for ABO-incompatible platelet transfusion. Alternatively identifying donors with high antibody titer or positive hemolysin test and selectively suspending their product in PAS may be a cost-effective approach and certainly prevent high-titer antibodies in the product.
