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

Convalescent plasma therapy (CPT) is one of the well-known therapeutic protocols for treating infectious diseases that do not have special treatment or vaccine. Several documents confirm the clinical efficacy of this therapy for treating bacterial and viral infections. A comprehensive systematic search was conducted by August 2020 using global databases including PubMed, Scopus, Embase, Cochrane library, Google scholar, medRxiv and bioRxiv. The Joanna Briggs Institute critical appraisal checklist was used to evaluate the included studies. Using the Comprehensive Meta-Analysis software version 2.2 (Biostat, Englewood, NJ, USA), the pooled data analysis process was performed. A total of 15 eligible articles were enrolled in the current quantitative synthesis. The statistical analysis showed that clinical improvement in the group of patients who had received convalescent plasma was significantly increased compared with the control group (OR: 2.23; 1.12-4.45 with 95% CIs;
