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
backgroundWide resection of soft tissue sarcomas (STS) of the hand and foot is challenging due to limited soft tissue and complex anatomy. Reconstruction often requires tissue from healthy donor sites. To address this, we used intraoperative extracorporeal irradiation (ECI) of tumor-affected bones and tendons for reconstruction after wide resection. Herein, we report the oncological and functional outcomes using this technique. CASE PRESENTATION: Three patients who underwent unplanned excision of the hand or foot at another institution referred to our hospital for additional treatment. Case 1: A 46-year-old man with extraskeletal myxoid chondrosarcoma on the dorsal aspect of the left hand underwent wide resection followed by ECI bone and extensor tendon reconstruction with free flap coverage, and subsequently required tenolysis. At 5 years, he showed no recurrence and excellent function (Musculoskeletal tumor society (MSTS) score, 100%; Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, 20.5). Case 2: A 27-year-old woman with synovial sarcoma of the dorsal right hand underwent wide resection and ECI bone and extensor tendon reconstruction. Delayed bone union required secondary bone grafting. She remained disease-free at 6 years with mild functional impairment (MSTS, 80%; QuickDASH, 29.5). Case 3: A 19-year-old woman with synovial sarcoma of the dorsal aspect of the right hallux underwent en bloc resection and ECI bone and extensor tendon reconstruction. At 4 years, she had no recurrence and excellent functional recovery (MSTS, 97%).
conclusionReconstruction using ECI-treated autogenous bone and tendon grafts allows effective oncological resection while preserving limb function and avoiding donor-site morbidity. Although mild degenerative changes were observed after osteoarticular reconstruction, all patients reported satisfactory outcomes and returned to their occupations. ECI is a valuable limb-salvage reconstruction option for STS of the hands and feet.
