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

caseAtypical fracture patterns, especially to the femur midshaft, have begun emerging since long-term bisphosphonate use was introduced. The same fracture pattern could arise around prosthetic hip implant, but the literature reports few cases regarding atypical periprosthetic femur fracture on previous total hip arthroplasty implant in patients on long-term bisphosphonate therapy. To our knowledge we report here the first case of atypical periprosthetic femur fracture arising after total hip arthroplasty implant on a previously identified but underestimated atypical femur pattern.

conclusionSurgeons should never underestimate an atypical femur pattern on x-rays and always relate groin and thigh pain to hip pathology before performing total hip arthroplasty.
