Estimation of short-course systemic corticosteroid risks on adverse outcomes in childhood asthma.

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
objectivesShort-course systemic corticosteroids (SCS) are recommended for moderate-to-severe pediatric asthma exacerbations, though frequent courses may cause adverse outcomes. We examined the risk of adverse outcomes in asthmatic children who received multiple SCS courses for exacerbation management.
methodsWe conducted a retrospective study of children aged 1–16 years with an asthma emergency department presentation/hospitalization between October 1, 2017, and February 28, 2021. Using a Prentice-Williams-Peterson total time model, we compared steroid-associated adverse outcomes among children who received or did not receive short courses of SCS for asthma exacerbations over ≥ 24-months.
resultsAmong 2009 eligible children, 1468 received ≥ 1 SCS course for asthma exacerbations and 541 did not receive SCS. Overall, there was no increase in the risk of recurrent SCS-associated adverse outcomes in those exposed to SCS (aHR = 0.95, 95% CI 0.74–1.23, p = 0.7), however, the number of SCS courses received significantly affected the risk of recurrent adverse outcomes (p = 0.029). Children receiving 2 SCS courses had a reduced risk of adverse outcomes (aHR = 0.49, 95% CI: 0.28–0.88), while those receiving ≥ 4 SCS courses experienced a non-significant, yet clinically meaningful elevated risk of adverse outcomes (aHR = 2.30, 95% CI 0.92–5.80).
conclusionThis study shows that SCS administered for pediatric asthma exacerbations are generally safe; however, complication risk may be increased when receiving 4 + SCS courses and synergistic with higher-dose inhaled corticosteroids.
