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
Purpose: This study aims to investigate the relationship between anterosuperior labral hypertrophy and other morphological parameters in hips with radiographically sufficient lateral coverage. Our hypothesis is that anterior undercoverage or combined high values of femoral torsion and acetabulaer version, represented as an increased McKibbin Index, would be associated with localized anterior labral hypertrophy. Methods: This was a retrospective case-control study at a single institution. A consecutive cohort was screened between January 2014 and September 2024 that received either magnetic resonance imaging (MRI) or MR-arthrography of the hip. Only hips with normal lateral centre edge angle values (between 25° and 40°) were included. Previously described radiographic parameters were evaluated: femoral torsion, acetabular version, Tönnis angle, anterior wall index (AWI), posterior wall index (PWI), McKibbin Index and labral height-to-length ratio on axial planes as a measure of anterior labral hypertrophy. Statistical analysis included Results: The McKibbin Index demonstrated a significant negative correlation with the labral height-to-length ratio on the axial plane ( Conclusion: Our findings highlight the correlation of the increased McKibbin index with anterosuperior labral hypertrophy and suggest relevant implications of the global rotational alignment, including both the acetabular version and femoral torsion on joint and labral biomechanics. Level of Evidence: Level IV.
