Fracture of a titanium femoral neck after revision total hip arthroplasty.
Article in BMJ case reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
We report a case of a fractured titanium alloy (Ti6Al4V) femoral stem 2 years after revision (debridement, antibiotics and implant retention due to periprosthetic joint infection) total hip arthroplasty (THA). Material analysis revealed a superficial abnormality on the upper neck surface caused by local melting with electrocautery probably acting as a stress amplifier. This lesion presumably was the trigger of a fatigue fracture with typical features on the fracture surface. Electrocautery should therefore be avoided in case of revision THA or used with utmost care to avoid contact with the femoral stem.
