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.

2 · The registry

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

backgroundLeft ventricular assist devices (LVAD) as a bridge (BTT) to heart transplantation (HTX) may be limited by the formation of anti-human leukocyte antigen antibodies. Whether sensitization occurs with continuous axial flow LVAD implant as assessed by single antigen bead (SAB) assay is unknown.

methodsCytotoxic panel-reactive antibody (PRA) and SAB assays were analyzed in HTX recipients undergoing LVAD implant as a BTT. Sensitization was defined as peak anti-human leukocyte antigen antibody values of more than 2000 mean fluorescence intensity because these values have been found to correlate with flow cytometric crossmatch results.

resultsLVADs were implanted as BTT in 30 patients. There were 7% (2 of 30) of patients before LVAD implant and no patients after LVAD implant with PRA more than 10%. However, 20% (6 of 30) of patients before LVAD and 53% (16 of 30) after LVAD were sensitized as measured by SAB (P=0.024). At HTX, 47% (14 of 30) of patients remained sensitized. A positive virtual crossmatch was observed in 28% (4 of 14) of the sensitized patients at HTX. There was no difference between the sensitized and nonsensitized groups (P>0.4 for all) in usage of blood products (6411 vs. 6339 units) and time to HTX (28,663 vs. 25,748 days), and 1 year after HTX, there were no differences in rejection (total rejection score 0.30 vs. 0.37) and survival (93% vs. 88%).

conclusionAllosensitization after LVAD is common despite cytotoxic PRA being negative. One year after HTX, this sensitization does not translate into increased acute cellular or antibody-mediated rejection or reduced survival.
