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

Objective To evaluate long-term radiographic and functional outcomes between dynamic hip screw (DHS) and proximal femoral nail antirotation (PFNA) fixation for treatment of osteoporotic type 31-A1 intertrochanteric femoral fractures (IFFs) among elderly patients Methods A retrospective comparative study was carried out. Follow-up was performed at 1, 3, 6, 9, and 12 months postoperatively and yearly thereafter. The primary outcome was the radiographic outcome, and the secondary outcome was the functional outcome. Results A significant difference in radiographic complications was observed between the DHS group (n = 45, 40.2%) and PFNA group (n = 15, 13.6%). The risk of femoral shaft fracture after implant removal at the 1-year follow-up was increased by 0.9% (n = 1) and 6.3% (n = 7) in the PFNA and DHS groups, respectively. This difference persisted with rates of 3.6% (n = 4) and 12.5% (n = 14) at the final follow-up. Additionally, significant differences were present in the Harris hip score at each visit. Conclusion Our results indicate that PFNA yields better outcomes than DHS fixation among elderly patients with osteoporotic type 31-A1 IFFs.
