Paving a way to treat spastic paraplegia 50.
Article in The Journal of clinical investigation, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Spastic paraplegia 50 (SPG50) is a rare neurodegenerative disease caused by loss-of-function mutations in AP4M1. There are no effective treatments for SPG50 or any other type of SPG, and current treatments are limited to symptomatic management. In this issue of the JCI, Chen et al. provide promising data from preclinical studies that evaluated the efficacy and safety profiles of an AAV-mediated AP4M1 gene replacement therapy for SPG50. AAV/AP4M1 gene replacement partly rescued functional defects in SPG50 cellular and mouse models, with acceptable safety profiles in rodents and monkeys. This work represents a substantial advancement in therapeutic development of SPG50 treatments, establishing the criteria for taking AAV9/AP4M1 gene therapy to clinical trials.
