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
backgroundCoronavirus Disease 2019(COVID-19) pneumonia, caused by the Severe Acute Respiratory Syndrome Coronavirus 2(SARS-CoV-2 virus), remains a significant global health challenge, contributing to millions of cases and deaths worldwide, including a substantial burden in Rwanda. Severe and critical cases often lead to respiratory failure, multi-organ dysfunction, and increased mortality. Despite global research, data on predictors of critical illness among hospitalized COVID-19 patients in Rwanda remain limited, highlighting the need for context-specific studies. This study aimed to assess the prevalence and identify risk factors for critical COVID-19 pneumonia among patients admitted to the Nyarugenge Major COVID-19 Referral Center in Rwanda.
methodsA mixed-study design combining retrospective and prospective designs was conducted from February to October 2021, and we included 320 patients aged 15 to 65 years admitted with severe or critical COVID-19 pneumonia. Data were collected on socio-demographic factors, vital signs, and clinical symptoms. Multivariate logistic regression was performed using Stata 17 to identify independent predictors of critical illness.
resultsOf the 320 patients, 30% presented with critical illness, while 70% had severe illness. Independent predictors of critical illness included oxygen saturation ≤ 90% {Adjusted Odds Ratio (AOR) = 5.83, 95% Confidence Interval(CI): 2.95-11.52, p < 0.001), respiratory rate > 20 beat per minute(bpm), (AOR = 2.34, 95% CI: 1.11-4.93, p < 0.05), and heart rate > 100 bpm (AOR = 2.49, 95% CI: 1.32-4.67, p < 0.01).
conclusionsCritical illness was prevalent in 30% of patients, with hypoxia, tachypnea, and tachycardia as significant predictors. These findings identify key clinical predictors of critical COVID-19 pneumonia and suggest that monitoring these indicators may help guide early intervention and optimize resource allocation in Rwanda and similar low- and middle-income settings.
