The effects of the antecedent use of inhaled steroid on the clinical course of COVID-19: A retrospective study of asthmatic patients.
Observational study in Journal of infection and public health, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundThere is conflicting evidence regarding the effect of asthma and its different therapeutic options on COVID-19 severity and the clinical outcomes.
aimThis study aimed to investigate the relationship between using inhaled corticosteroids (ICS) by asthmatic patients and the severity of COVID-19. MATERIALS AND
methodsThis retrospective observational study was conducted from March 15 to October 23, 2020 and included data of all COVID-19 asthmatic patients (n = 287) at King Abdulaziz Medical City. Twelve patients were excluded due to poor medication history documentation or using ICS for non-asthma indication. Ordinal logistic regression was used to determine the clinical variables that affect COVID-19 severity. The clinical outcomes of ICS and non-ICS users were compared.
resultsOf the sample (n = 275), 198 (72%) were using ICS therapy. No significant difference was found between ICS and non-ICS users in disease severity (P = 0.12), mortality (P = 0.45), ICU admission (P = 0.78), and the occurrence of complications. However, the number of days on ventilation were significantly increased in ICS users (P = 0.006). Being prescribed the ICS/LABA combination (adj OR: 0.72 [0.15,1.2]; P = 0.021), being hypertensive (adj OR: 0.98 [0.28,1.6]; P = 0.006), having cancer (adj OR: 1.49 [0.12, 2.8]; P = 0.033), or having diabetes (adj OR: 0.75 [0.09, 1.4]; P = 0.024) could not increase the risk for more severe disease.
conclusionOverall, ICS therapy did not alter the COVID-19 severity or mortality in asthmatic patients. The continued use of ICS during the pandemic should be encouraged to prevent asthma exacerbations.
