Comparison of leg length discrepancy after total hip arthroplasty: Direct anterior and posterior lateral approach.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundLeg length discrepancy (LLD) after total hip arthroplasty (THA) is a clinical entity that deteriorates clinical outcomes and patients' satisfaction. Few articles have compared LLD after THA by different surgical approaches.
methodsA total of 358 consecutive patients who underwent primary THA between January 2016 and November 2018 were retrospectively reviewed. All 4 surgeons performed THA through both direct anterior approach (DAA) and posterior lateral approach (PLA). The primary outcome measurement was LLD. LLD was measured on post-operative anteroposterior bilateral hip radiograph. The secondary outcomes were acetabular abduction, acetabular anteversion, perceived LLD (pLLD) and HHS at 6 weeks, 1 year and 5 years. Intergroup analyses were performed using the Chi-square test for enumeration data and the independent sample t-test for quantitative data.
resultsThere was no inter-group difference in terms of patients' demographics. The DAA group had decreased LLD compared to the PLA group (3.0 ± 5.9mm vs. 4.2 ± 4.5mm, p = 0.027). Meanwhile, the DAA group had a smaller acetabular anteversion than the PLA group (12.9 ± 2.9 vs. 18.4 ± 2.9, p < 0.01). At 6-week follow-up, the DAA group had higher HHS (82.2 + 6.2 vs. 80.5 + 6.6, p = 0.015) and less pLLD (P = 0.001) compared to the PLA group.
conclusionsDAA results in more accurate leg length equalization, reduced pLLD, and improved short-term outcomes compared with PLA.
