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

backgroundCan the helical blade in proximal femur nailing antirotation (PFNA) reach a better bony fixation than proximal femur nailing (PFN), thereby decreasing complication rates and improving clinical outcomes especially in osteoporotic bone? MATERIALS AND

methodsIn a retrospective study complications and clinical treatment results of pertrochanteric and subtrochanteric femoral fractures were analyzed. For this purpose a group of patients stabilized with PFN (n=65) were compared to a patient group treated with PFNA (n=66). Objective and subjective parameters were acquired and analyzed by clinical follow-up studies using the Merle d'Aubigné score and X-ray evaluation. Individual bone quality was analyzed radiologically by determining the Singh index. The mean follow-up time was 7 months in each group.

resultsThe PFNA showed a decrease in postoperative implant-associated complications especially in osteoporotic bone and unstable fracture types.

conclusionThe philosophy of the PFNA blade with better fixation through an increased implant-bone-interface and smaller cross-section, compaction of cancellous bone as well as an antirotational fixation, seems to show advantages compared to the double screw system of the PFN.
