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

backgroundConvalescent plasma treatment for severe and critically ill Corona Virus Disease 2019 (COVID-19) patients remains controversial.

objectiveTo evaluate the clinical improvement and mortality risk of convalescent plasma treatment in patients with severe and critically ill COVID-19 patients.

methodsA literature search was conducted in the electronic databases for the randomized controlled studies about convalescent plasma therapy in severe and critically ill COVID-19 patients. Two reviewers independently extracted relevant data. The primary outcomes were clinical improvement and mortality risk of severe and critically ill COVID-19 patients that were therapied by convalescent plasma.

resultsA total of 14 randomized controlled trials with 4543 patients were included in this meta-analysis. Compared to control, no significant difference was observed for either clinical improvement (6 studies, RR 1.07, 95% CI 0.97 to 1.17, p = 0.16, moderate certainty) or mortality risk (14 studies, RR 0.94, 95% CI 0.85 to 1.03, p= 0.18, low certainty) in patients of convalescent plasma therapy group.

conclusionConvalescent plasma did not increase the clinical improvement or reduce the mortality risk in the severe and critically ill COVID-19 patients.
