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
Objective: To investigate the relevant risk factors for bronchitis obliterans and develop a predictive nomogram for bronchitis obliterans in children with severe Mycoplasma pneumoniae pneumonia(SMPP). Methodology: This was a retrospective study. This study analyzed the clinical data of Xingtai People's Hospital, Xingtai Emergency Center children with SMPP from September 2021 to September 2025, and categorized them into the bronchitis obliterans and PB groups. SPSS 26.0 statistical software was used for data organization and analysis. Results: Four hundred and sixty-four children with SMPP were finally included, of which 27(5.8%) children with PB were complicated by bronchitis obliterans. According to the chi square test and Mann Whitney U test, it was found that the gender, age, duration of fever, duration of cough, white blood cells, neutrophils, eosinophils CRP, alanine aminotransferase IL-6, IL-10, the comparison of tumor necrosis factor, APTT, D-dimer, aspartate aminotransferase, immunoglobulin E, and immunoglobulin G showed no statistically significant differences(P>0.05). The lactate dehydrogenase levels in patients with bronchitis obliterans were higher than those in patients with PB(P<0.05). The immunoglobulin A levels in patients with bronchitis obliterans were lower than those in patients with(P<0.05). The results showed that a higher level of LDH was an independent risk factor for bronchitis obliterans, while a higher level of immunoglobulin A was an independent protective factor for bronchitis obliterans. Conclusion: The increase of lactate dehydrogenase is an independent risk factor for bronchitis obliterans. The lactate dehydrogenase and immunoglobulin A have good sensitivity and specificity for building a nomogram prediction model for the risk of bronchitis obliterans.
