Atelectasis and lung changes in preterm neonates in the neonatal period: a blind radiological report and clinical findings.
Observational study in Revista Brasileira de terapia intensiva, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectiveTo determine the occurrence and characteristics of atelectasis, opacities, hypolucency and pulmonary infiltrates observed on chest X-rays of preterm infants in a neonatal intensive care unit.
methodsThis was a cross-sectional observational study. From August to December 2017, all chest radiographs of newborn infants were analyzed. The study included the chest radiographs of preterm neonates with gestational ages up to 36 weeks in the neonatal period that showed clear changes or suspected changes, which were confirmed after a radiologist's report. Radiological changes were associated with possible predisposing factors.
resultsDuring the study period, 450 radiographs were performed on preterm neonates, and 37 lung changes were identified and classified into 4 types: 12 (2.66%) changes were described as opacities, 11 (2.44%) were described as atelectasis, 10 (2.22%) were described as pulmonary infiltrate, and 4 (0.88%) were described as hypolucency. A higher occurrence of atelectasis was noted in the right lung (81.8%). Among the abnormal radiographs, 25 (67.6%) newborn infants were receiving invasive mechanical ventilation.
conclusionConsidering the radiological report, no significance was found for the observed changes. Atelectasis was not the most frequently observed change. The predisposing factors for these changes were extreme prematurity, low weight, male sex, a poorly positioned endotracheal tube and the use of invasive mechanical ventilation.
