Methylprednisolone in the management of post-COVID-19 interstitial lung disease: A randomized trial (STERCOV-ILD).

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
BACKGROUND AND
aimPost-COVID-19 Interstitial Lung Disease (ILD) is controversial and need for treatment is unclear.The aim of this study was to investigate the efficacy of methylprednisolone in the management of post-COVID-19 ILD in comparison to standard of care.
methodsIn this multicentre, randomized controlled clinical trial, patients with post-COVID ILD were assigned to two groups: the steroid group received oral methylprednisolone at a dose of 0.5 mg/kg/day, while the control group received supportive therapy. The primary outcome was proportion of patients with functional improvement (defined as the absence of hypoxemia/desaturation during 6MWT) at twelve-weeks.
resultsA total of 229 patients with post-COVID ILD patients (124 in the steroid group and 104 in the control group) completed the study. At 12-weeks, functional improvement rate was higher in the steroid group compared to the control group (74.2% vs. 55.2%, OR:2.33 [95% CI:1.34-4.06], p=0.0041). Radiological improvement was observed in 61.3% of the steroid group compared to 46.7% of the controls (OR:1.81 [95% CI:1.07-3.06], p=0.037). The mean increase in FVC (7.2% vs 3.7%, p=0.03), 6MW distance (91 vs 41 meters, p<0.001), and SpO2 (2.33 vs 1.21, p=0.002) was significantly higher in the steroid group. Multivariate regression analysis revealed that the following variables were associated with poorer outcomes: smoking (OR:0.932 [95% CI:0.875-0.992], p=0.028), older age (OR:0.951 [95% CI:0.912-0.99], p=0.035), and severe COVID-19 (OR:0.233 [95% CI:0.068-0.799], p=0.029.
conclusionsMethylprednisolone improved oxygen saturation, FVC, exercise capacity, and radiological resolution in patients with post-COVID-19 ILD compared to the natural course of the disease.
