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

aimThe treatment algorithm for end-stage ankle arthritis is imperfect. Young or active patients are challenging to treat as fusion and replacement carry predictable consequences. Ankle distraction arthroplasty is a less commonly utilized surgical procedure for the treatment of osteoarthritis of the ankle. The purpose of this study was to report intermediate-term survival of ankle distraction and to identify factors associated with earlier time to failure. MATERIALS AND

methodsA single-centre, multi-surgeon cohort of 258 cases of ankle arthritis, treated with ankle distraction or ankle distraction with supramalleolar osteotomy (SMO), was identified. Patients were contacted by phone to determine the status of the ankle (natural vs fused/replaced). Data were collected through chart review. This included patient demographics, medical comorbidities, surgical procedure, and X-ray characteristics including pattern and severity. A Cox regression model was used to determine factors associated with failure during 10 years of follow-up. Risk factors were analysed as hazard ratios (HRs) and 95% confidence intervals (CIs). Time to failure was illustrated with Kaplan-Meier (KM) curves.

resultsIn total, 144 cases were successfully contacted with median follow-up of 4.57 years. In total, 16.7% of ankles failed (24/144). The 5-year survival was 84% (95% CI: 78-91%). In adjusted Cox regression, female sex (HR = 2.68,

conclusionAvascular necrosis of the talus and male/female gender differences in survival were found to be significant. Our experience shows that ankle distraction is a valid and effective operation for the treatment of end-stage ankle arthritis. CLINICAL SIGNIFICANCE: This work is clinically significant in that it demonstrates excellent intermediate-term survival data for hinged ankle distraction for treatment of osteoarthritis of the ankle. Additionally, it evaluated patient and disease characteristics allowing improved patient counselling with regard to survival longevity. LEVEL OF EVIDENCE: IV cohort study.
