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

purposeArthroscopic ankle arthrodesis is known to offer high fusion rates, improvements in pain and functional outcomes, low risks of complications, and reinterventions. The aim of this study is to compare open vs. arthroscopic ankle arthrodesis in patients at high risk of complications.

methodsA single-centre retrospective comparative analysis of ankle fusions was conducted. Patient records were screened for demographics, type of arthrodesis, follow-up length, pre-operative diagnosis, risk factors for non-union, operative time, radiographic union, time to union, complications, and reinterventions. The American Orthopedic Foot & Ankle Society (AOFAS) Ankle-Hindfoot Scale, the Italian version of the Foot Function Index (FFI), and a visual analog scale (VAS) for pain scores collected pre-operatively and in the last follow-up were used to assess clinical outcomes.

resultsThere were 23 open and 21 arthroscopic ankle fusions. Union rate was higher (90.5% vs. 65.2%, p < 0.05) and complication rate was lower (14.3% vs. 47.8%, p < 0.05) in the arthroscopic group. In addition, patients who underwent arthroscopic arthrodesis reported better pain control, with higher improvements in VAS for pain scores. There was no significant difference in length of operative time, time to fusion, AOFAS, and FFI scores improvements between the two groups.

conclusionsArthroscopic ankle arthrodesis resulted in higher union rates, fewer complications, and lower reoperation rates in patients at high risk of complications.
