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
purposeChronic osteomyelitis with large bone defects remains a challenging condition in orthopedic surgery. This study aimed to evaluate the clinical efficacy of hemicorticotomy bone transport assisted by 3D-printed customized guides in the treatment of chronic osteomyelitis with bone defects.
methodsA retrospective analysis was conducted on 21 patients with chronic osteomyelitis treated with hemicorticotomy bone transport with 3D-printed guide assistance between January 2015 and January 2021. Preoperative planning utilized 3D CT reconstruction for precise guide design and osteotomy placement. The surgical technique involved hemicorticotomy, placement of the 3D-printed guide, and gradual bone transport using a monolateral external fixator. Clinical outcomes were assessed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) scoring system. The external fixation time (EFT), external fixation index (EFI), and complications evaluated using the Paley classification were recorded.
resultsThe mean bone defect size was 7.9 ± 2.0 cm. The average follow-up period was 28.6 ± 6.4 months. The mean external fixation time was 289.4 ± 52.7 days, with an external fixation index of 36.8 ± 4.2 days/cm. According to the ASAMI criteria, the bone results were excellent in 17 patients (81%), good in 3 (14%), and fair in 1 (5%). The functional results were excellent in 15 patients (71%), good in 4 (19%), and fair in 2 (10%). Complete eradication of the infection and union at the docking site were achieved in all patients. The complication rate was 38% and all of which were successfully managed.
conclusionHemicorticotomy bone transport assisted by 3D-printed customized guides is an effective treatment for chronic osteomyelitis with bone defects. This technique offers excellent bone healing, favorable functional results, and a relatively low complication rate. Further studies with larger sample sizes are warranted to validate these findings.
