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: Protracted bacterial bronchitis (PBB) is a leading cause of chronic wet cough in children. Misdiagnosis and inadequate treatment may lead to the progression of diseases. Objective: The objective of this paper was to analyze factors influencing the cough duration prior to the diagnosis and assess health-related quality of life in children with PBB. Methods: Children diagnosed with PBB in the Qilu Hospital of Shandong University from November 2021 to November 2022 were included in this study. Clinical data were collected; parents completed the Parent-Proxy Cough-Specific Quality of Life (PC-QOL) questionnaire and the simplified Cough Symptom Score. Children aged 6 years and older completed the Leicester Cough Questionnaire in Mandarin-Chinese (LCQ-MC). Results: As of November 2022, we enrolled 88 patients. Place of residence (B=9.35, 95% CI 0.36-18.35; P=.04) and rest status during the coughing episode (B=7.87, 95% CI 0.36-15.38; P=.04) were significantly associated with cough duration prior to the diagnosis. PC-QOL scores (physical: mean 3.10, SD 1.36; psychological: mean 3.32, SD 1.57; social: mean 3.67, SD 1.53; total: mean 10.09, SD 4.21) showed physical-social differences (t174=-2.58, P=.01). PC-QOL posttreatment scores were significantly higher than pretreatment scores (physical: t18=-6.05, P<.001; psychological: t18=-4.42, P<.001; social: t18=-4.79, P<.001; total: t18=-5.25, P<.001). However, the scores of each PC-QOL domain were significantly lower than those of the LCQ-MC (physical: t34=8.31, P<.001; psychological: t34=6.58, P<.001; social: t34=5.09, P<.001; total: t34=8.11, P<.001). Conclusions: Place of residence and rest status during the coughing episode were significantly associated with cough duration prior to the diagnosis. Furthermore, PBB significantly reduces quality of life in physical, psychological, and social aspects.
