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
introductionSpinal muscular atrophy (SMA) is a progressive neuromuscular disorder associated with respiratory complications and reduced quality of life (QOL). Although disease-modifying therapies have altered the clinical course of SMA, the role of home-based respiratory physiotherapy as an adjunct to pharmacologic treatment remains underexplored. The aim of this study is to evaluate the impact of a 1-year home-based respiratory physiotherapy program on QOL and pulmonary function in nusinersen-treated patients with SMA types 2 and 3.
methodsThis mixed prospective interventional and retrospective analytical study assessed the impact of weekly home-based, personally tailored respiratory physiotherapy sessions in addition to standard multidisciplinary care. Group allocation was determined by patient or parental willingness to participate and geographical feasibility for weekly home visits. Pulmonary function tests (PFTs) were performed at baseline and after 12 months. QOL was assessed with the SF-36 questionnaire and the Global Rating of Change (GROC) scale.
resultsTwenty-nine patients with spinal muscular atrophy (SMA) types 2 and 3 receiving nusinersen were included. The intervention group (n = 15) and the control group (n = 14) were comparable at baseline. Objective respiratory parameters remained stable in both groups with no significant differences at the end of the intervention (forced vital capacity % predicted: 72.7 ± 25.1 in the intervention group vs. 69.4 ± 26.5 in the control group, p = 0.7). In contrast, the intervention group demonstrated significantly higher scores in multiple SF-36 domains, including physical functioning and energy/fatigue (41.3 ± 43.7 vs. 2.1 ± 3.7 and 71.7 ± 16.9 vs. 51.4 ± 14.5, respectively; p < 0.05). The median GROC score in the intervention group was 3.0, indicating a clinically meaningful perceived benefit in QOL by exceeding the minimal clinically important difference threshold.
conclusionHome-based respiratory physiotherapy was associated with stable pulmonary indices as well as significant improvements in perceived health status and QOL in patients with SMA treated with nusinersen.
