Risk factors for multiple bronchoalveolar lavage procedures in children with severe or refractory Mycoplasma pneumoniae pneumonia.
Article in Jornal de pediatria. 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
objectiveTo identify factors influencing how often bronchoalveolar lavage (BAL) is performed in children with severe or refractory Mycoplasma pneumoniae pneumonia (MPP) and provide evidence to guide early intervention.
methodsClinical data for 271 children with severe or refractory MPP who underwent BAL at the studied institution between May 1, 2023, and April 30, 2024, were retrospectively divided according to the number of BAL procedures into a single-treatment group (STG, n = 219) and a multiple-treatment group (≥ 2 times; MTG, n = 52). Risk factors for multiple BAL procedures in these children were identified by logistic regression and receiver-operating characteristic curve analyses.
resultsPeak body temperature was significantly higher, duration of fever was significantly longer, and pulmonary consolidation, pleural effusion, atelectasis, mucus plug formation, and pulmonary lesions involving two or more lung lobes were significantly more common in the MTG than in the STG (all P < 0.05). The white blood cell count, neutrophil percentage, and C-reactive protein (CRP), lactate dehydrogenase (LDH), fibrinogen, and D-dimer levels were significantly higher and the lymphocyte percentage was significantly lower in the MTG (P < 0.05). Logistic regression and receiver-operating characteristic curve analyses showed that mucus plug formation, CRP ≥ 25.68 mg/L, LDH ≥ 374.90 U/L, and D-dimer ≥ 1.22 mg/L were independent risk factors for multiple BAL in children with severe or refractory MPP.
conclusionMucus plug formation and increased CRP, LDH, and D-dimer levels are important risk factors for multiple BAL in children with severe or refractory MPP. Pediatricians should strengthen management and early intervention in these children to avoid the harm caused by multiple BAL procedures.
