Clinical characteristics and predictor analysis of pediatric Mycoplasma pneumoniae pneumonia with small segment molded sputum plugs: a retrospective study.
Article in Italian journal of pediatrics, 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
backgroundThis study aimed to analyze the clinical characteristics and identify predictive factors associated with small segment molded sputum plugs in pediatric patients with Mycoplasma pneumoniae pneumonia (MPP).
methodsA retrospective analysis was performed on the clinical data of pediatric patients diagnosed with MPP who underwent bronchoscopy at our hospital between December 2021 and April 2024. Multivariate logistic regression was employed to determine independent predictors of small segment molded sputum plug formation.
resultsAmong 116 pediatric patients with MPP who met the study criteria, 48 (41.38%) were found to have small segment molded sputum plugs, while 68 (58.62%) did not. Patients with a history of recurrent respiratory infections, diminished breath sounds, and radiological evidence of atelectasis were significantly more likely to develop molded sputum plugs (P < 0.05). Furthermore, the group with small segment molded sputum plugs exhibited a longer duration of fever (P = 0.025) and elevated levels of procalcitonin (PCT; P = 0.024), alanine aminotransferase (ALT; P = 0.048) and prothrombin time (PT; P = 0.021). Multivariate logistic regression analysis identified a history of recurrent respiratory infections and diminished breath sounds as independent predictors for the development of small segment molded sputum plugs.
conclusionsA history of recurrent respiratory infections and diminished breath sounds emerged as independent predictors of small segment molded sputum plugs in pediatric MPP. These findings highlight the importance of considering these clinical features during the evaluation of MPP patients to inform diagnostic and therapeutic decision-making. Future studies are warranted to investigate the potential benefits of early detection and intervention on clinical outcomes in pediatric MPP.
