The long-term efficacy of nusinersen on respiratory functions in children with symptomatic spinal muscular atrophy type 1.

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/aim: Available data regarding the effects of nusinersen on respiratory function in the real-world setting are uncertain. We aimed to evaluate the impact of nusinersen on respiratory outcomes over a follow-up period of up to 72 months in patients with symptomatic spinal muscular atrophy type 1 (SMA type 1). Materials and methods: Respiratory status was defined similarly to previous studies: spontaneous breathing, noninvasive ventilatory support for ≤16 h per day, and permanent assisted ventilation. The planned evaluation time was day 180 (after the fourth dose), day 300 (after the fifth dose), and after the last injection for patients who received nusinersen for 2 years or more. Results: Our cohort consisted of 32 patients. The mean age at treatment initiation was 6.6 months (range: 2.5-16 months). Twenty-eight of 32 patients were eligible for evaluation after the fourth dose. Twenty-three of 28 patients were eligible for assessment after the fifth dose of nusinersen. Eight Conclusion: Improvement in respiratory function in patients treated with nusinersen for 2 years or more is generally not expected in the natural course of the disease. However, in our cohort, patients treated with nusinersen mainly maintained their current respiratory status, and many patients required ventilatory support despite treatment with nusinersen. Therefore, our findings may reflect the limited efficacy of nusinersen in symptomatic patients.
