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

Objective: To systematically evaluate the impact of probiotic supplementation on wound-specific and systemic clinical outcomes in critically ill patients. Methods: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) according to PRISMA guidelines. A comprehensive search of six databases was performed up to December 31, 2025. We included RCTs of probiotic/synbiotic interventions in adult ICU patients reporting wound-related outcomes. Study quality and evidence certainty were assessed using Cochrane RoB 2.0 and GRADE frameworks. Data were pooled using random-effects models. Results: Nineteen RCTs involving 1,384 patients were included. Probiotic supplementation significantly reduced the risk of wound infection (RR = 0.52, 95% CI: 0.38-0.71), with the most pronounced benefit observed in burn patients. It also significantly reduced hospital length of stay (MD = -5.24 days, 95% CI: -8.73 to -1.75) and the duration of antibiotic use (SMD = -0.18, 95% CI: -0.25 to -0.11), and the duration of mechanical ventilation (SMD = -0.90, 95% CI: -1.20 to -0.60). Probiotics were associated with reduced systemic inflammation (CRP SMD = -0.73, 95% CI: -1.15 to -0.32) and improved intestinal barrier function (RR = 1.63, 95% CI: 1.28-2.08). However, no significant effect was found on wound healing time (MD = -5.60 days, 95% CI: -23.09 to 11.88). While overall mortality was not significantly reduced (RR = 0.75, 95% CI: 0.56-1.01, Conclusion: Moderate-certainty evidence indicates that probiotic supplementation may serve as a beneficial adjunct in critical care, primarily for preventing wound infections and reducing hospital stay and mechanical ventilation duration, with particular efficacy in burn patients. Its effect on accelerating wound healing remains inconclusive. Future research should focus on standardizing interventions and evaluating long-term outcomes.
