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

backgroundThe preferred treatment of intertrochanteric fractures in aged patients is controversial. The purpose of the present study was to evaluate the outcomes of the Asian proximal femur intramedullary nail antirotation system (PFNA-II) for stabilization of such fractures.

methodsThe PFNA-II was used to treat intertrochanteric fractures in 163 elderly patients from March 2010 to March 2013. The patients comprised 69 men and 94 women with a mean age of 74.7 ± 13.0 years. All fractures were classified by the Orthopaedic Trauma Association classification system; 53, 83, and 27 fractures were classified as 31A1, 31A2, and 31A3, respectively. We statistically evaluated the intraoperative blood loss, operation time, incision length, X-ray exposure time, and postoperative outcomes. Patients were followed up for a mean of 15.2 months (range, 10-24 months). Functional outcomes were assessed according to the Harris hip scoring system.

resultsStatistical analysis revealed an average operation time of 45.7 min (range, 35-110 min), average intraoperative blood loss of 115.2 mL (range, 65-430 mL), X-ray exposure time of 2.7 ± 1.4 s (range, 2-6 s), and total incision length of 6.5 ± 2.2 cm (range, 5.5-13.0 cm). Patients were followed up for a mean of 14.5 months (range, 10-24 months). The neck shaft angle was 134° ± 15° (range, 115°-150°), and the fracture healing time was 14.0 ± 2.5 weeks (range, 11-19 weeks). The Harris hip score was 85.6 ± 17.5 points (range, 65-100 points) and included 41 excellent cases (25.15%), 92 good cases (56.44%), 26 moderate cases (15.95%), and 4 poor cases (2.45%) for a positive outcome rate of 81.60%. There were no varus hip deformities, screw cutouts, or femoral shaft fractures. Fourteen patients had thigh pain (9.82%), and five had inner thigh pain (3.07%); seven had more severe pain that was improved by physical therapy.

conclusionPFNA-II has the advantages of a simple operation, few complications, and clinical efficacy for the treatment of intertrochanteric fractures. However, evaluation of its long-term efficacy and risk of other complications requires a large-sample, multicenter observational study.
