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

backgroundOne-fifth of patients with femoroacetabular impingement (FAI) have bilateral symptoms. Performing bilateral hip arthroscopy on the same day minimizes the overall rehabilitation period compared with staged bilateral surgery, but most studies of outcomes from simultaneous surgery are in small cohorts. PURPOSE/HYPOTHESIS: The purpose was to compare clinical outcome and revision rates between patients undergoing simultaneous bilateral, staged bilateral, and unilateral arthroscopic surgery for FAI from a large single-surgeon cohort. It was hypothesized that there would be no between-group differences. STUDY

designCohort study; Level of evidence, 3.

methodsSimultaneous bilateral, staged bilateral, and unilateral primary hip arthroscopy procedures between June 2005 and December 2020 were identified. Patient-reported outcome measures including the 12-item International Hip Outcome Tool (iHOT-12) score, Non-Arthritic Hip (NAH) score, and Hip Disability and Osteoarthritis Outcome Score (HOOS) were collected preoperatively and at regular intervals postoperatively. Two-year follow-up scores were analyzed if they were available, or later follow-ups if they were not. Subsequent surgery rates were recorded utilizing a compulsory national joint replacement registry.

resultsA total of 196 patients (392 hips) in the simultaneous bilateral and 111 patients (222 hips) in the staged bilateral groups were compared with 1529 patients in the unilateral group. The median duration between staged surgeries was 62 days (range, 14-350 days), and demographic characteristics were similar for those having simultaneous and staged procedures. Two-year minimum postoperative scores in all 3 groups were significantly improved from preoperative scores (

conclusionPatients undergoing simultaneous bilateral arthroscopy for FAI achieved similar 2-year follow-up outcomes compared with staged and unilateral arthroscopy and performed better than the staged group in Sports and Quality of Life subscales of the HOOS.
