Cup alignment in total hip arthroplasty using the muscle-sparing modified Watson-Jones approach-comparison between lateral and supine positions.
Article in International orthopaedics, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
purposeThe present study aimed to compare the cup alignment outliers in total hip arthroplasty (THA) using the same surgical approach with the patient in the supine position versus the lateral position.
methodsTHA using the muscle-sparing modified Watson-Jones approach was performed in 142 consecutive hips. THA was performed with the patient in the lateral position in 84 hips (lateral group) and in the supine position in 58 hips (supine group). The cup alignment was aimed at 40° inclination and 20° anteversion by referring to the mechanical alignment guide. Cup alignment and outliers (10° > aimed alignment) were assessed using post-operative 3D-CT.
resultsThe absolute error from the aimed inclination was 6.0 ± 4.7° in the supine group and 4.2 ± 3.6° in the lateral group (p = 0.01). The absolute error from the aimed anteversion was 4.1 ± 3.2° in the supine group and 5.1 ± 3.7° in the lateral group (p = 0.12). The supine group showed a higher rate of outliers than the lateral group for the cup inclination (22% vs 5%; p < 0.01). Inclination and BMI were positively correlated in the spine position group (p < 0.01, R = 0.48), but were not correlated in the lateral position group.
conclusionTHA performed with the patient in the supine position has a higher risk of outliers of cup alignment compared with the lateral position, even when the same surgical approach is used. BMI affected the cup inclination in the supine position.
