1 · What the graph read from 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.

2 · The registry

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 and Objectives: Limb-girdle muscular dystrophy (LGMD) type R1/2A, calpain-3-related, is a rare, autosomal recessive disorder caused by pathogenic variants in the Methods: Ninety-two individuals were evaluated by physiotherapy teams at Nationwide Children's Hospital and the John Walton Muscular Dystrophy Research Centre. Psychometric analysis of NSAD and PUL was completed using Rasch measurement methods. Descriptive statistics and correlation coefficients explored the relationship among all outcomes. Results: Psychometric analyses demonstrated that NSAD and PUL were valid and appropriate functional outcome measures for ambulant and nonambulant individuals with LGMDR1/2A. The NSAD and 100MTT velocity were highly correlated (Spearman rho Rs(88) = 0.89) The 100MTT was particularly useful for the strongest and asymptomatic cohort. Discussion: In this largest reported cohort of individuals with LGMDR1/2A, NSAD, PUL, and 100MTT were suitable to quantify functional impact of the disease. International harmonization of outcome measures creates meaningful clinical data to inform clinical management and trial design.
