1 · What the graph read from it

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.

Abstract

backgroundThe clinical significance of natural and treatment-emergent antibodies specific for amustaline/glutathione pathogen-reduced red blood cells (PRRBCs) is not known. STUDY DESIGN AND

methodsA Phase 3, randomized clinical trial of PRRBCs (ReCePI) compared PRRBCs with conventional RBCs in cardiac or thoracic-aorta surgery. Subjects transfused during and for 7 days after surgery were screened for PRRBC-specific antibodies at baseline, 28 and 75 days post-surgery. Subjects with treatment-emergent antibodies were assessed for evidence of hemolysis. Cryopreserved subject RBC samples were assayed by flow cytometry for circulating PRRBCs using an acridine-specific (2S197-2M1) monoclonal antibody, and for human IgG-coated RBCs. RBC-surface acridine density was quantitated using a commercial calibrated phycoerythrin (PE)-bead panel.

resultsFive of 159 (3.1%) PRRBC and zero of 162 conventional RBC recipients developed treatment-emergent PRRBC-specific IgG, low titer antibodies detected 26-80 days post-surgery after exposure to 1-3 PRRBC units, without clinical evidence of hemolysis. DAT and eluate were weak (w+) positive and PRRBC-specific in one subject. A monocyte monolayer assay (MMA) was non-reactive in the three subjects with an interpretable result. Flow cytometry demonstrated circulating PRRBCs in all five subjects expressing surface acridine concentrations at the limit of detection (approximately 150-301 PE molecules/RBC) compared with freshly transfused PRRBCs (approximately 7500 PE molecules/RBC). In some samples, loss of surface acridine expression could not be distinguished from clearance of the PRRBCs. DISCUSSION: Treatment-emergent PRRBC-specific antibodies with the characteristics of nonclinically significant antibodies were detected in five subjects transfused with PRRBCs. Flow cytometry demonstrated persistent circulating PRRBCs with minimal surface acridine expression. (www. CLINICALTRIALS: gov Identifier NCT03459287).
