Clinical usefulness of the Ottawa Ankle Rules in the overweight and obese population following an acute ankle injury: A prospective cross-sectional study.

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
objectiveThe aim of this study was to determine the clinical usefulness of the Ottawa Ankle Rules (OAR) in overweight and obese patients compared to the general population.
methodsIn this prospective cross-sectional study, 935 adult patients (453 female, 482 male; mean age = 57.2 ± 20.9) admitted to the emergency department following an acute ankle injury (<3 days) secondary to low energy-trauma were included. All the patients were examined based on a standardized protocol, including age, Body-Mass Index (BMI), OAR, and presence of ankle fracture. As accuracy indicators, sensitivity, specificity, positive and negative predictive values of OAR were calculated.
resultsOf all patients, 790 (84.5%) were normal weighted, 107 (11.5%) were overweight, and 38 (4%) were obese. While OAR was negative in 58.8% of patients, 41.2% of patients met OAR. The sensitivity of OAR in the normal weighted population was significantly higher than obese and overweight groups (P < 0.01). The specificity of OAR in the normal weighted population was significantly lower than overweight and obese groups (P < 0.01). The accuracy of OAR in the overweight group was 82.7% and significantly higher compared with the normal weighted population (62.8%) (P < 0.01).
conclusionWe do not recommend OAR as a screening tool to be used safely in patients with higher BMI because of its lower sensitivity in this population. In this specific patient population, these rules should be implemented carefully, and radiography should be evaluated meticulously not to miss a fracture. LEVEL OF EVIDENCE: Level IV, Cross Sectional Study.
