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
Aims: Open fractures pose a substantial treatment challenge, with adjacent muscle loss being a major complication. The induced membrane (IM) technique has shown promise in treating complicated fractures. The aim of this study is to investigate the impact of adjacent muscle trauma on segmental fracture healing using recombinant human bone morphogenetic protein-2 (rhBMP-2) via the IM technique. Methods: Skeletally mature male rats (n = 10 to 11 per group) underwent unilateral 3 mm segmental bone defects (SBD) of the tibial diaphysis or a composite tissue injury (CTI), which included a SBD along with volumetric muscle loss (VML). A polymethyl methacrylate (PMMA) spacer was formed within the SBD of each rat. After a four-week period, the PMMA spacer was removed, and the defect was treated with a rhBMP2-impregnated collagen sponge. Longitudinal micro-CT (µCT) imaging was conducted at baseline (Day 0) and at weeks 2, 4, 8, and 12 post-spacer removal to monitor fracture healing progress. At the 12-week postoperative mark, a comprehensive analysis was conducted, including endpoint µCT analysis, evaluation of neuromuscular function, tibia torsional testing, and histological examination. Results: Longitudinal µCT scans revealed no differences in bone formation or bone mineral density (BMD) at any timepoint between the SBD and CTI groups. High-resolution µCT analysis at the endpoint also showed no variations in bone quality. Torsion testing confirmed that VML did not affect bone strength. Notably, CTI animals exhibited an irreversible reduction in muscle mass and neuromuscular function, which was not observed in the SBD group. Conclusion: Introducing the additional challenge of VML alongside SBD did not hinder the effectiveness of the induced membrane technique in healing a critical-sized defect.
