1 · What the graph read from it

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.

2 · The registry

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

objectiveTo investigate the surgical technique and clinical efficacy of the Nice knot combined with cannulated screws for Beavis Type II posterior calcaneal tuberosity avulsion fractures in osteoporotic elderly patients.

methodsA retrospective analysis was conducted on 18 osteoporotic elderly patients with Beavis Type II posterior calcaneal tuberosity avulsion fractures treated at our institution between June 2019 and December 2024. All patients underwent open reduction and internal fixation using a Nice knot combined with cannulated screws. Postoperative assessment included radiographic review supplemented by evaluation of complication rates, fracture healing time, time to full weight-bearing, and the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot score.

resultsAll 18 patients achieved radiographic union with a follow-up of 12-18 months (mean 13.00 ± 1.85 months). Complications comprised delayed wound healing in two cases, which resolved with regular dressing changes, and periwound paraesthesia in one case that resolved after three months of mecobalamin treatment. The mean time to clinical fracture union was 12.22 ± 1.35 weeks, and the mean time to full weight-bearing was 10.00 ± 1.68 weeks. At final follow-up, the mean AOFAS ankle-hindfoot score was 85.94 ± 6.40, with an excellent/good rate of 77.78%. There were no instances of loss of reduction, implant loosening, or hardware failure.

conclusionThis preliminary study suggests that the Nice knot combined with cannulated screw technique offers stable fixation, promotes early rehabilitation, and results in a low complication rate in osteoporotic elderly patients with Beavis type II avulsion fractures. However, the retrospective design, small sample size, and absence of a control group limit how broadly these findings can be applied. These preliminary results need validation through future prospective, multicenter randomized controlled trials with larger sample sizes.
