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
purposeTo evaluate and compare clinical and radiological outcomes of surgical strategies for osteochondritis dissecans (OCD) lesions across ICRS grades, and to investigate the impact of recipient hole drilling (RHD) as a biological augmentation to osteochondral grafting.
methodsThis retrospective study included 60 knees (ICRS grades 1-4) treated surgically from 2001 to 2022. Stable lesions (grade 1) were managed with either retrograde or antegrade drilling with bioabsorbable pin fixation. For unstable lesions (grades 2-3), in situ osteochondral autograft transfer (OATS) or detach-and-fix techniques were performed. Detached lesions (grade 4) underwent either mosaicplasty or fragment fixation. RHD was introduced in select OATS and mosaicplasty cases to stimulate subchondral bone remodeling. Outcomes were assessed using the Lysholm and Tegner scores and MOCART-based MRI evaluations. Statistical comparisons were performed across groups.
resultsAntegrade drilling resulted in significantly higher Lysholm, Tegner, and MOCART scores than retrograde drilling for ICRS grade 1 lesions. In situ OATS for ICRS 2-3 lesions showed superior clinical and radiological outcomes compared to detach-and-fix, with no reoperations. For ICRS 4 lesions, both mosaicplasty and fragment fixation yielded favorable outcomes, though only Tegner scores showed a significant difference. RHD tended to improve cartilage repair quality in OATS and mosaicplasty but did not reach statistical significance.
conclusionsAntegrade drilling and in situ OATS were superior to retrograde drilling and detach-and-fix, respectively. No statistically significant advantage was found between mosaicplasty and fragment fixation. RHD may enhance subchondral integration and healing, supporting its further evaluation. CLINICAL RELEVANCE: Optimizing OCD treatment requires surgical strategies that achieve both mechanical stability and biological activation. Integrating these principles may enhance repair quality and long-term joint preservation. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
