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

objectivesThe aim of this study was to determine whether convalescent blood products (CBPs) offer a survival advantage for patients with severe acute respiratory infections of viral etiology.

methodsUp-to-date trials were identified by the authors through searches of the MEDLINE, Embase, Cochrane Library, Web of Science, ClinicalTrials.gov, and medRxiv databases from inception up to September 14, 2020. Meta-analyses were performed using a random-effects model.

resultsAccording to the observational studies, patients who received CBPs showed a decline in all-cause mortality compared with patients who did not receive CBPs (odds ratio (OR) 0.36, 95% confidence interval (CI) 0.23-0.56; p < 0.00001). However, the randomized controlled trials (RCTs) showed no difference between the intervention group and the control group regarding all-cause mortality (OR 0.82, 95% CI 0.57-1.19; p = 0.30). The use of CBPs did not increase the risk of adverse events (OR 0.88, 95% CI 0.60-1.29; p = 0.51). Using CBPs earlier compared with using CBPs later was associated with a significant reduction in all-cause mortality (OR 0.18, 95% CI 0.08-0.40; p < 0.0001).

conclusionsBased on the outcomes of RCTs, CBPs may not decrease all-cause mortality. Furthermore, compared with later initiation of CBP therapy, earlier initiation of this therapy may decrease the rate of mortality.
