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: The majority of children with COVID-19 infection experience asymptomatic or mild disease, but some of them are at risk of developing severe illness. Determination of predictors of severe disease can help to prevent this form of disease in children. The aim of the current study was to determine the predictors of disease severity of COVID-19 infection based on laboratory markers and underlying conditions in children. Methods: This cross-sectional study was conducted in Iran from May 2021 to March 2022. Thirty hundred and seventeen children under 18 years old with positive tests or pulmonary manifestations of COVID-19 referred to a teaching hospital in Tehran were included in the study. Demographic, laboratory, and clinical parameters of included children were measured. The participants were classified into three severity groups based on a severity-scoring protocol. Data was analyzed using SPSS software with chi-square, analysis of variance (ANOVA) tests, and linear generalized model. Statistical significance was considered at 0.05. Results: Among 317 children, 186 patients (58.7%) were male. The mean age of the participants was 4.75 ± 4.47 years old. Examination of clinical factors showed cough (64%), Malaise (57.7%), and Tachypnea (35.3%) were the most frequent findings among the subjects. Employing the severity scoring protocol, most patients (69.1%) were classified into the mild group. There was a significant relationship between the severity of COVID-19 and the level of Hemoglobin, Aspartate Transaminase (AST), Alanine Transaminase (ALT), C-reactive protein (CRP), Lactate Dehydrogenase (LDH), Creatine Kinase (CK), D-dimer, Ferritin, and Fibrinogen ( Conclusion: In our study, it was determined that CK could be considered a predictor of the severity of COVID-19 in children. These results suggest that integrating CK assessment into routine clinical protocols may aid healthcare providers in timely risk stratification and personalized patient care approaches.
