Diaphragmatic pacing for spinal cord injury patients: impact on weaning rate - a systematic review and meta-analysis.
Synthesis in BMC pulmonary 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
backgroundSpinal cord injury (SCI), particularly when affecting the high cervical region, frequently results in diaphragmatic paralysis and subsequent reliance on mechanical ventilation. Although life-sustaining, mechanical ventilation presents its own set of limitations and potential complications. A thorough, quantitative evaluation of diaphragmatic pacing (DP) as an alternative intervention, specifically regarding its influence on weaning success rates in SCI patients, has been notably absent. This investigation aimed to address these existing knowledge gaps.
methodsTwo independent researchers conducted a systematic search across PubMed, Embase, the Cochrane Library, and Web of Science databases, encompassing all publications from their inception until March 17, 2025. Eligibility criteria prioritized within-cohort comparative studies involving SCI patients undergoing DP, which reported weaning rate. The risk of bias was evaluated using the ROBINS-I tool. A meta-analysis was subsequently performed utilizing Cochrane Review Manager 5.4, employing a random-effects model to account for clinical and methodological heterogeneity.
resultsThe meta-analysis ultimately incorporated 6 articles. All six studies reported weaning rate after diaphragmatic pacing. The pooled weaning success rate was 75% (95% CI: 69%-81%) with no statistical heterogeneity ([Formula: see text], [Formula: see text]).
conclusionDiaphragmatic pacing appears to be associated with a substantial weaning success rate among individuals with spinal cord injury. Nevertheless, these findings warrant cautious interpretation due to the prevalence of non-randomized study designs, restricted sample sizes, and inherent clinical heterogeneity across the included literature, resulting in a Very Low certainty of evidence as per GRADE assessment. Consequently, further high-quality, large-scale randomized controlled trials are imperative to substantiate these conclusions.
