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 explore the efficacy and feasibility of arthroscopy combined with bone tunnel technique in treating Berndt and Harty stage III or IV osteochondral lesions of the talus (OLT).
methodsA retrospective analysis was conducted on the clinical data of 21 patients with Berndt and Harty stage III or IV OLT who underwent surgical treatment at our institution from September 2017 to September 2022. Under arthroscopy, the displaced talar osteochondral lesion was restored. A 2.0 mm Kirschner wire (K-wire) was used to create a bone tunnel from the medial (or lateral) malleolus to the realigned osteochondral lesion. A 1.5 mm K-wire was then used to drill through this tunnel into the osteochondral fragment, and a 1.5 mm absorbable bone rod was inserted for fixation. Preoperative and final follow-up visual analogue scale (VAS) for pain and American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot scale were recorded and compared.
resultsAll 21 patients were followed up for an average of 23.95 ± 6.01 months. All wounds healed by primary intention, with no nerve, blood vessel, or tendon injuries. All osteochondral lesions healed, with an average healing time of 3.71 ± 0.62 months. The VAS score decreased from a preoperative average of 5.38 ± 0.59 to 0.48 ± 0.51 at the final follow-up. The AOFAS ankle-hindfoot scale increased from a preoperative average of 56.29 ± 5.98 to 88.43 ± 2.68 at the final follow-up (P < 0.05), showing statistically significant differences. Two cases experienced medial pain after 12 months, which was tolerable with non-steroidal anti-inflammatory drugs.
conclusionArthroscopy combined with bone tunnel technique for treating Berndt and Harty stage III or IV OLT has the advantages of minimal injury, visualization of fracture reduction, and fewer complications.
