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
objectiveThis study aimed to evaluate the functional and radiographic outcomes of full arthroscopic subtalar joint arthroscopy combined with a calcaneal distractor for the management of Sanders type II and III calcaneal fractures.
methodsA retrospective analysis was conducted on 26 patients (26 feet) with Sanders type II and III calcaneal fractures who underwent treatment utilizing a full arthroscopic subtalar arthroscopy technique combined with a calcaneal distractor. The surgeries were performed in the Department of Orthopedics at Xuzhou Central Hospital between January 2019 and December 2022. The cohort included 20 males and 6 females, with a mean age of 47.96 ± 8.87 years (range: 34-66 years). According to the Sanders classification, 7 fractures were type II and 19 were type III. Preoperative assessments yielded the following scores: a mean Visual Analogue Scale (VAS) score for pain of 7.35 ± 1.06 points (range: 4-9), a mean American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score of 52.27 ± 9.52 points (range: 55-85), and a mean SF-36 quality of life score of 92.04 ± 4.88 points (range: 80-100).All patients underwent fixation via the combined subtalar joint arthroscopy and calcaneal distractor approach. Postoperative evaluations focused on wound healing status, quality of fracture reduction, and evidence of bony union. Functional outcomes and pain levels were assessed using the VAS, AOFAS ankle-hindfoot score, and the SF-36 questionnaire. A comparison of preoperative and final follow-up scores was performed using the independent samples t-test.
resultsAll procedures were successfully completed without intraoperative complications. The mean operative time was 69.7 ± 10.4 min (range: 40-110). All surgical incisions achieved primary healing, with no instances of soft tissue infection, necrosis, or sensory disturbances observed during the postoperative period. Postoperative radiographic measurements of the calcaneus, including its length, width, height, Böhler's angle, and Gissane's angle, demonstrated significant improvement compared to preoperative values (all P < 0.01). Furthermore, no statistically significant differences were observed in these parameters between the immediate postoperative period and the final follow-up (all P > 0.05), indicating well-maintained fracture reduction and satisfactory healing. The patients showed significant improvement in the VAS, AOFAS, and SF-36 scores postoperatively compared to their preoperative status (all P < 0.01). At the final follow-up, functional outcomes were satisfactory. According to the AOFAS ankle-hindfoot scale, the scores were graded as excellent in 24 cases and good in 2 cases, yielding an excellent-good rate of 100.0%.
conclusionThe combined technique of full arthroscopic subtalar arthroscopy and a calcaneal distractor demonstrates high precision in fracture reduction and satisfactory clinical outcomes, establishing it as a reliable and effective method for managing Sanders type II and III calcaneal fractures.
