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

Purpose: The transverse acetabular ligament (TAL) plays a pivotal role in determining cup anteversion during total hip arthroplasty (THA). Meanwhile, the kinematic alignment (KA) technique focuses on restoring the native hip anatomy and adjusting cup orientation based on the TAL. This study aims to investigate whether utilizing the TAL or TAL-based KA as a guide for aligning cup anteversion satisfies the functional requirements of THA. Methods: This retrospective study included 92 patients (107 hips; 40 men and 52 women). TAL anteversion was assessed using computed tomography scans. Radiographic inclination angles were standardized at 40°. The analysis involved comparing the ratios of TAL and TAL-based KA to determine their alignment with the criteria of the Lewinnek safe zone (LSZ), combined sagittal index (CSI) ante-inclination (AI) criteria, and patient-specific safe zone (PSSZ). Results: The mean TAL anatomical anteversion (AA) angle was 18.90 ± 5.56°. No significant difference was observed between the left and right sides ( Conclusions: The TAL or TAL-based KA for aligning cup anteversion does not consistently satisfy the functional requirements of THA. Level of Evidence: Level III.
