Article in Clinics in orthopedic surgery, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 14 registered trials, which are not on this map. Cited by 228 papers, 1 of them a synthesis that pooled 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.
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.
