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

Background: Organising pneumonia is an interstitial lung disease linked to infections and other conditions. Cryptogenic organising pneumonia is a rarer, idiopathic form. Organising pneumonia has become one of the most frequent respiratory complications following severe acute respiratory syndrome coronavirus 2 pneumonia. Standard treatment involves the use of glucocorticoids. The objective of the study is to determine the optimal dosage of oral corticosteroids for the treatment of this disease. Methods: Randomised, open-label, assessor-blinded, parallel-group, single-centre, noninferiority clinical trial with an active control group comparing two oral prednisone regimens. The control group received prednisone 0.75 mg·kg Results: 79 patients were randomised according to intention-to-treat group, 40 to the experimental group and 39 to the control group. Mean±sd baseline Conclusions: Treatment with oral corticosteroids lasting 3 months (initial dose of prednisone 0.5 mg·kg
