Assessment of exertional capacity using the six-minute step test in COVID-19 survivors six months after hospitalization: a prospective observational study in Paraíba, Brazil.

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.
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
Survivors of Coronavirus Disease (COVID-19) frequently report persistent symptoms and reduced exercise capacity after hospital discharge. Simple, accessible methods to assess exertional performance in this population are urgently needed. We conducted a prospective observational study to evaluate exertional capacity using the six-Minute Step Test (6MST) in adults who had been hospitalized for COVID-19 at a referral center in Paraíba, Brazil. Participants were assessed six months after discharge using clinical evaluation, spirometry, standardized questionnaires (mMRC - modified Medical Research Council, SF-12 - Short Form-12), chest computed tomography and 6MST. The primary outcome was the number of steps completed on the 6MST. Performance was compared with normative values. Multivariable regression was used to identify predictors of poor exertional performance. Among 102 eligible participants, 88 (86.3%) completed the 6MST. The mean number of steps was 132.8 ± 30.9. 37.8% performed below the predicted threshold for healthy individuals; 10% fell below the 10th percentile. In the final multivariable model (R
