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

Several case series and multiple individual case reports suggest that some subtrochanteric and femoral shaft fractures might occur in patients who have been treated with long-term bisphosphonates. Several unique clinical and radiographic features are emerging: prodromal thigh pain prior to the fracture, complete absence of trauma precipitating the fracture, and bilateral fractures in some patients. Radiographic features include presence of stress reaction, transverse or short oblique fractures, and thick femoral cortices. The overall incidence of subtrochanteric and shaft fractures combined is below 30 per 100,000 person-years, so this type of fracture is much less common than proximal femur (hip) fracture. Furthermore, the unique "atypical" fracture type is a subset of all subtrochanteric and femoral shaft fractures. The putative mechanism is unknown, and more research is needed to identify distinctive characteristics and the pathophysiology of these atypical fractures. There is no rationale to withhold bisphosphonate therapy from patients with osteoporosis, although continued use of bisphosphonate therapy beyond a treatment period of 3 to 5 years should be re-evaluated annually.
