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

Purpose: The learning curve of a single surgeon performing hip arthroscopy is reported to be steep, but, to date, the inflection point after which procedures are more successful is still unknown. The aim of this study was to design a learning curve focused on clinical outcomes, complications and revision/conversion rates. Methods: Seventy-one hip arthroscopies performed for femoroacetabular impingement (FAI) by a single surgeon, with a minimum follow-up of 5 years, were considered. Demographics, intraarticular findings and operative and traction time were detailed. HOOS score, subjective outcomes, 30-day complication rates, complication rates, revision arthroscopies and conversions to hip arthroplasty were recorded. Results: The mean follow-up was 7.5 ± 1.8 years (range: 5-11). The progression of the learning curve implied a reduction in surgical time ( Conclusions: The inflection point of the hip arthroscopy learning curve is between 25/36 procedures. The first arthroscopies were impacted by higher complications and lower clinical results but no higher rates of revision and conversion to arthroplasty. Level of Evidence: Level IV.
