Exploring Peripheral and Respiratory Muscle Weakness and Functional Impairments in ICU Patients: Insights From a Resource-Constrained Setting.
Observational study in Critical care explorations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
IMPORTANCE AND
objectivesThe aim of this study was to explore peripheral and respiratory muscle structure and strength from unit admission to hospital discharge among ICU patients in a resource-constrained setting.

participantsNewly intubated critically ill adults admitted to the medical and surgical ICUs and expected to be mechanically ventilated for more than 48 hours were included in the study. MAIN OUTCOMES AND MEASURES: Ultrasonography of the right hemi-diaphragm and quadriceps muscles were taken at admission for 3 consecutive days. Respiratory and peripheral muscle strength were evaluated using the Medical Research Council-Sum Score, dynamometry and maximal inspiratory pressure (MIP) at awakening, ICU discharge and hospital discharge.
resultsForty-five participants were included, with a median (interquartile range) age of 34.5 (24.3-47.4) years and 73% were male. Most of the change in diaphragm thickness was observed on day 3, with 5 (22%) participants showing a decrease of more than 10% from baseline. Minimal changes in rectus femoris cross-sectional area were noted during the first 3 days. Eleven participants (44%) presented with ICU-acquired weakness at awakening, which decreased to 7 (29%) participants at ICU discharge and 5 (24%) participants at hospital discharge. The mean ± sd percentage of predicted quadriceps force was 22.2 ± 5.1 N at hospital discharge. The mean ± sd percentage of predicted MIP scores was 29.6% ± 10.5% at ICU discharge and 29.1% ± 8.6% at hospital discharge. CONCLUSIONS AND RELEVANCE: Patients discharged from the ICU in a resource-constrained setting presented with peripheral and respiratory muscle weakness, with minimal change in muscle structure shown by ultrasonography, despite short ICU stays, low Acute Physiology and Chronic Health Evaluation II scores, and a relatively young age. Future research should explore whether these findings indicate a distinct phenotype of critical illness in such environments.
