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

Purpose: This study sought to compare the risk of subtrochanteric stress-riser fractures and biomechanical stability of the Femoral Neck System (FNS) versus multiple screw fixation (MSF). Methods: Eight paired cadaveric femurs were randomly assigned to FNS or MSF. Physiologic load mimicking single leg stance at the subtrochanteric region was applied to the constructs. Results: No constructs failed in the subtrochanteric region during loading. There was no significant difference in force (P = 0.364) or loading cycles (P = 0.348) between groups. Conclusion: FNS constructs were not associated with an increased incidence of iatrogenic subtrochanteric fractures or biomechanical stability versus MSF.
