Observational studyAnnals of cardiac anaesthesia
A Lung ultrasound-based comparison of postoperative respiratory outcome after pediatric congenital heart surgery in COVID-19 recovered and COVID-19 unaffected children-a pilot study.
Observational study in Annals of cardiac anaesthesia. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper, 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
Background: COVID-19 is known to affect the alveolar-capillary membrane and interstitial tissue. Cardiopulmonary bypass (CPB) is proven to cause "pump-lung" syndrome. Little is known about the subgroup of COVID-19-recovered children undergoing cardiac surgeries under CPB. Aim: To compare the lung ultrasound score (LUSS) and morbidity of COVID-19-recovered children to those without COVID-19 after congenital cardiac surgery. Setting and Design: Prospective observational pilot study at a tertiary care institution. Materials and Methods: The study was carried out on 15 COVID-recovered children and 15 matched controls (Group B) posted for congenital cardiac surgery. COVID-recovered children were further divided into those who received in-hospital care for COVID (Group C) and those who did not (Group A). LUSS measured immediately after cardiac surgery was compared between the groups. PaO Results: LUSS was comparable between Groups A and B (mean difference = 1.467, P = 0.721). Compared to the control group, Group C showed higher LUSS (mean difference = 11.67, P < 0.001), lower PaO Conclusion: LUSS was not higher in COVID-recovered children. Children with a history of severe COVID-19 recorded higher LUSS, in-hospital mortality, duration of ICU stay, and duration of ventilation.
