Timing of surgery after fever resolution in children with SARS-CoV-2: a prospective cohort study.
Article in BMJ open respiratory research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundFever in children with SARS-CoV-2 infection may increase the risk of intraoperative oxygen desaturation during surgery. This study seeks to find the optimal surgery timing by examining oxygen desaturation rates after fever resolution.
methodsA prospective cohort study from March to August 2023 included children with SARS-CoV-2 infection who were scheduled for surgery after fever resolution. The primary outcome was the incidence of intraoperative oxygen desaturation. Logistic regression models were used to calculate the adjusted incidence of oxygen desaturation, stratified by time intervals from fever resolution to the day of surgery: 0-2 weeks, 3-4 weeks, 5-6 weeks, 7-8 weeks and ≥3 months.
resultsThe intraoperative oxygen desaturation rate was 7.96%. It was highest in the 0-2 weeks group (18.3%), lower in the 3-4 weeks group (11.5%), and further decreased in the 5-6 weeks (6.8%), 7-8 weeks (4.7%) and ≥3 months (4.9%) groups. Adjusted analysis showed significantly higher oxygen desaturation risk in the 0-2 weeks (adjusted OR (aOR), 5.56; 95% CI 3.76 to 8.21) and 3-4 weeks (aOR, 3.31; 95% CI 2.15 to 5.09) groups compared with the ≥3 months group. Risk factors for intraoperative oxygen desaturation included younger age, higher Body Mass Index (BMI), an abnormal chest radiograph and ongoing symptoms (all p<0.05).
conclusionsTo minimise the risk of intraoperative oxygen desaturation, elective surgeries in paediatric patients should be scheduled no earlier than 4 weeks after fever resolution.
