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.
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
backgroundHip resurfacing arthroplasty (HRA), a viable alternative to total hip arthroplasty (THA), is often constrained by postoperative complications that are closely related to the orientation of femoral prosthesis. Although avoiding varus placement is widely accepted, the optimal prosthesis orientation remains unclear. This study aims to determine the optimal orientation of femoral prosthesis in HRA from a biomechanical perspective.
methodsA three-dimensional finite element model of the hip joint was developed based on CT data and incorporated a Birmingham Hip Resurfacing prosthesis. Five orientations were simulated: 30° varus, 15° varus, neutral, 15° valgus, and 30° valgus. A physiological load of 2100 N was applied to evaluate contact pressure, peak von Mises stress (VMS), and principal strain distributions in both the prosthesis and proximal femur.
resultsAt 30° varus, the highest peak VMS (204.0 MPa) and strain (6.12 × 10⁻
conclusionA 15° valgus orientation may represent the biomechanically optimal position for femoral prosthesis placement in HRA, effectively minimizing mechanical stress and strain while preserving physiological load transfer patterns. These findings offer practical guidance to enhance implant longevity and reduce the risk of postoperative complications.
