Nusinersen for spinal muscular atrophy types II and III: a retrospective single-center study in South Korea.
Article in World journal of pediatrics : WJP, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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 investigated the efficacy and safety of nusinersen, an antisense oligonucleotide, in patients with spinal muscular atrophy (SMA) types II (OMIM: 253,550) or III (OMIM: 253,400), including those with severe scoliosis or requiring respiratory support via mechanical ventilation.
methodsData from 40 patients with genetically confirmed SMA who were treated with nusinersen at our institute from March 2019 to April 2022 were retrospectively analyzed. Of these, 30 patients with an age of onset < 3 years and not on permanent ventilation were selected. Clinical and genetic characteristics were investigated, and motor function was evaluated based on the Hammersmith Functional Motor Scale-Expanded (HFMSE) score.
resultsThe mean age of symptom onset was 1.2 years. Most patients were diagnosed with SMA type II (27/30, 90%). Nusinersen was administered via computed tomography-guided or direct intrathecal injection in 87% (26/30) and 13% (4/30) of the patients, respectively. At the 6-, 14-, 22-, and 26-month follow-ups, 72%, 71%, 88%, and 86% of patients showed motor improvement, respectively, with mean changes in HFMSE scores of 2.10, 2.88, 4.21, and 5.29, respectively. Multivariable analysis showed that the use of noninvasive ventilation was associated with poorer outcomes of motor function.
conclusionsPatients with SMA type II or III who received nusinersen treatment showed significant improvement in motor function. A longer treatment duration led to a higher number of patients with improved motor function. No significant side effects of nusinersen were observed. Patients with SMA, even those with severe scoliosis or on respiratory support, can be safely treated using nusinersen.
