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

A case of total knee replacement loosening caused by a failed cephalomedullary nail is presented. The nail was inserted for the treatment of an unstable subtrochanteric femoral fracture. The distal locking screw of the nail subsequently fractured allowing the leg to shorten and causing the nail to displace the femoral component of the knee replacement leading to a valgus alignment and deformity of the knee. In order to revise the knee the long γ nail had to be replaced by a shorter nail to allow a femoral component with a long stem to be used. This case illustrates the importance of using shorter nails in patients with prosthetic knees.
