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
Purpose: Recalcitrant diabetic foot ulcers (DFUs) remain difficult to heal and impose substantial clinical and economic burdens. This exploratory, four-arm, parallel-group randomized pilot trial aimed to evaluate whether combining platelet-rich plasma-fibrin glue (PRP‑FG) with a novel repairing gel enhances healing outcomes in DFUs compared with standard care and single‑agent therapies. Patients and Methods: In this study, twenty patients with DFUs unresponsive to at least four weeks of standard treatment were randomized using computer-generated blocks with allocation concealment to receive PRP‑FG alone, repairing gel alone, the combination therapy, or standard care. Allogeneic PRP‑FG was prepared by gradient‑density centrifugation. The repairing gel contained multiple active components, including vitamins A, B3, and C, collagen, glycine, organic acids, sodium alginate, carboxymethyl cellulose, benzoic acid, gentian violet, methylene blue, triethanolamine, bromelain, allantoin, and dimethyl sulfoxide. Wound healing rate over 12 weeks served as the primary outcome, assessed weekly by a blinded evaluator. Results: Nineteen patients completed the 12‑week follow‑up. Complete epithelialization occurred in 100% (5/5) of participants receiving the combined therapy, 20% (1/5) of those receiving the repairing gel alone, and 0% (0/5) in the PRP‑FG alone and standard care groups. The combined therapy significantly accelerated ulcer healing compared with all other groups (p < 0.05). These findings are preliminary and derived from a small pilot sample. No serious adverse events were observed. Conclusion: This exploratory pilot trial suggests that combined PRP‑FG and repairing gel therapy may promote superior healing of recalcitrant DFUs compared with standard care or single‑agent treatments. Larger, multicenter clinical trials are warranted to validate these preliminary findings.
