Cementing technique of the femur in primary THA: the French paradox.
Article in EFORT open reviews, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
The French paradox cementing technique encompasses a canal filling highly polished stem with a thin (<1 mm) cement mantle. The technique has been developed by Pr Marcel Kerboull in the late 1960s after he observed the patterns of debonding of the original Charnley stem. The key point of the technique is based upon removal of the metaphyseal cancellous bone (with hollow reamers or aggressive broaches) especially at the supero-medial region. Only two stems have been validated with this technique: the Charnley-Kerboull (CK) and the Ceraver Osteal stem, both of which are collared. This technique is neither a taper slip (the stem does not subside at long-term follow-up) nor a composite beam (a highly polished stem is used). A 12% shortened stem CK has shown similar results to the standard-length stem, including the absence of stem subsidence. Combined with the Hueter anterior approach, this technique has demonstrated one of the lowest femoral PPF rate in elderly patients in the literature.
