Correlation of diaphragmatic ultrasound with pulmonary function testing in patients with chronic cervical spinal cord injury: A single center pilot study.
Article in The journal of spinal cord medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
CONTEXT/
objectivePulmonary function tests are the gold standard of evaluating pulmonary function in individuals with a spinal cord injury (SCI). However, there are limitations to its accessibility thereby reducing its clinical utility. Diaphragmatic ultrasound is used to evaluate pulmonary function in non-neurologic individuals but there is limited evidence demonstrating its benefit in individuals with SCI. The objective is to determine if diaphragmatic ultrasound measurements are correlated with forced vital capacity (FVC), peak cough flow (PCF), neurological level of injury (NLI), and/or motor level. DESIGN &
settingA pilot study at a single rehabilitation hospital.
participantsIndividuals ≥18yo with traumatic and non-traumatic SCI for ≥6 months with NLI from C1-C6, and ASIA Impairment Scale scores A, B, or C.
interventionsN/A. OUTCOME MEASURES: Associations between FVC, PCF, and diaphragmatic ultrasound measurements (thickness at total lung capacity, thickness at functional residual capacity, and right diaphragm excursion). Also, associations between diaphragmatic ultrasound measurements with NLI and motor level.
resultsSignificant associations were detected between the thickening ratio and FVC (
conclusionDiaphragmatic ultrasound is a promising tool in the evaluation of two parameters of pulmonary function in those with cervical SCI. A larger, longitudinal study to confirm these findings and evaluate for normative values would be beneficial.
