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

purposeThe primary goal of this randomised controlled trial was to investigate whether there are differences in the outcome between the Gamma3 nail and a sliding hip screw (SHS) regarding quality of life 1 year after surgery.

methodsIn a controlled randomised trial, we compared the Gamma3 nail (Stryker) and a SHS (Omega, Stryker) in the treatment of 193 patients with pertrochanteric fractures. The follow-up period was 12 months. The outcomes included the surgical duration, health-related quality of life measured with the EQ-5D Index and a Visual Analogue Scale (VAS), the living situation and use of walking aid before trauma and 52 weeks after surgery; the Parker Mobility Score; the Harris Hip Score; and the revision, complication and mortality rates.

resultsThe Gamma3 group had a significantly shorter surgical duration than the SHS group (p < 0.0001). Implant-related complications were significantly lower in the Gamma3 group (p > 0.05). The revision rate was significantly lower in the Gamma3 group based on intention-to-treat (p = 0.0336) as well as as-treated (p = 0.0302) analyses. Otherwise, we did not find significant difference between the two groups regarding the EQ-5D Index and VAS scores, the Parker Mobility Score, the Harris Hip Score, the mortality rate, the use of walking aids and the living situation.

conclusionThere were no detectable differences between the groups in terms of quality of life and clinical scores 12 months after surgery. The surgical duration and revision rate were superior for the Gamma3 group.
