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: We analyzed the prevalence and clinical characteristics of children with plastic bronchitis (PB) caused by severe Mycoplasma pneumoniae (SMPP) and explored its risk factors. Methods: This retrospective study included pediatric patients with SMPP who were admitted to the Respiratory Department of Children's Hospital of Soochow University and underwent fiberoptic bronchoscopy (FB) treatment between January 1 and December 31, 2024. The SMPP patients were divided into a PB group and a non-PB group according to whether there was a plastic shape under FB. Epidemiological characteristics, general information, clinical manifestations, laboratory findings, imaging features, and treatment regimens were collected and compared between the two groups. Risk factors for PB were identified using logistic regression analysis, and their predictive value was assessed with receiver operating characteristic (ROC) curves. Results: This study incorporated a total of 510 children diagnosed with SMPP, with 60 and 450 assigned to the PB and non-PB groups, respectively. The epidemic peak of SMPP occurred in summer and autumn; the highest detection rate of PB was recorded in winter (19.30%), with the PB positivity rate peaking in December (32.26%). In the PB group, fever days, runny nose, diminished breath sounds, abnormal liver function, abnormal coagulation function, number of bronchoscopic interventions, neutrophil percentage, C-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), D-dimer, atelectasis, and pleural effusion were all significantly higher compared to the non-PB group ( Conclusion: LDH, pleural effusion, and length of hospital stay were independent risk factors for PB in SMPP children. For children suspected of PB, pediatricians should pay close attention to the above indicators, strive for early diagnosis and treatment, and improve prognosis.
