Motor Unit Number Index (MUNIX) in Control Children: Reference Values and Reliability.
Article in Muscle & nerve, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
INTRODUCTION/
aimsThe motor unit number index (MUNIX) is recognized as a reliable electrophysiological biomarker, and reference values are available for healthy adults but not for children. The aim of this study was to determine reference MUNIX values in healthy children.
methodsSixty control children (28 females) were grouped as under 5 years (n
resultsThe APB MUNIX increased by 6.5 [95% confidence interval, 3.2-9.7] per year of age, 1.0 [0.5-1.5] per cm, and 1.7 [0.4-4.0] per kg (p < 0.001 in each case), but was not independently associated with either of these three variables in multivariable analysis. The APB compound muscle action potential (CMAP) increased by 0.42 [0.30-0.52] per year of age, 0.06 [0.04-0.08] per cm, and 0.11 [0.07-0.14] per kg (p < 0.001 in each case), and increased with age independently of height and weight at borderline significance (p = 0.065). Measurement reproducibility was high for the experienced investigator, but lower between the experienced and the inexperienced investigator. DISCUSSION: The high intra-investigator reproducibility for the experienced investigator indicates that these parameters are useful electrophysiological biomarkers for disease progression and potential treatment response.
