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
In the context of severe coronavirus disease 2019 (COVID-19) illness, we examined endogenous glucocorticoid concentrations, steroidogenic enzyme activity, and their correlation with inflammation and patient outcomes. This observational study included 125 hospitalized COVID-19 patients and 101 healthy individuals as a reference group. We utilized LC-MS to assess serum concentrations of 11-deoxycortisol, cortisol, and cortisone, as well as activities of steroidogenic enzymes (11β-hydroxylase and 11β-hydroxysteroid-dehydrogenase type 1). Cox proportional hazards regression analysis and competing risk analysis were employed to analyze associations between glucocorticoid concentrations and outcomes, adjusting for relevant factors. In patients with COVID-19, cortisol concentrations were higher and cortisone concentrations were lower compared to the reference group, while 11-deoxycortisol concentrations were similar. Steroidogenic enzyme activity favored cortisol production. Correlations between glucocorticoid concentrations and inflammatory markers were low. A doubling in concentrations cortisol, was associated with increased 90-day mortality and mechanical ventilation (HR: 2.40 95% CI: (1.03-5.59) , P = 0.042 and HR: 3.83 (1.19-12.31), P = 0.024). A doubling in concentrations of 11-deoxycortisol was also associated to mortality (HR: 1.32 (1.05-1.67), P = 0.018), whereas concentrations of cortisone were associated with mechanical ventilation (HR: 5.09 (1.49-17.40), P = 0.009). In conclusion, serum concentrations of glucocorticoid metabolites were altered in patients hospitalized with severe COVID-19, and steroidogenic enzyme activity resulting in the conversion of cortisone to biologically active cortisol was preserved, thus not favoring critical-illness-related corticosteroid insufficiency at the enzymatic level. Glucocorticoid release did not counterbalance the hyperinflammatory state in patients with severe COVID-19. High serum concentrations of 11-deoxycortisol and cortisol were associated with 90-day mortality, and high serum concentrations of cortisol and cortisone were associated with mechanical ventilation.
