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
introductionThis study presents clinical und functional long-term outcomes up to 10 years after primary total hip arthroplasty (THA) without concomitant surgical intervention and a far proximal cup positioning.
methods33 patients (44 hips) underwent primary THA for severe dysplastic hip osteoarthritis with a far proximal cup position. Hips were divided into two groups: Group A (n = 27) with cups positioned at 55-65 mm and Group B (n = 17) with cups positioned > 65 mm from the interteardrop line. Functional outcomes were assessed at 114 ± 15 months postoperatively using LEFS, HHS, HOOS, and Tegner Activity Score. Patient satisfaction and leg length difference were also evaluated. Statistical analysis employed the Mann-Whitney U test (p < 0.05 significance level).
resultsThe study found no significant differences in the two groups in terms of functional results, as measured by HOOS (89.1 ± 12.1 vs. 89.0 ± 8.3; p = 0.5145), LEFS (66.7 ± 13.1 vs. 68.7 ± 11.5; p = 0.5544), and HHS (95.1 ± 7.4 vs. 94.9 ± 4.4; p = 0.2707). Both groups showed very good functional results. The Tegner Activity Score significantly improved in both groups from preoperative to final follow-up (A: 2.1 ± 1.4 to 4.0 ± 0.7; p = 0.0002; B: 1.8 ± 1.1 to 3.9 ± 1.1; p = 0.0009). There were no significant differences found when comparing the pre- and postoperative leg length differences (p = 0.5793). No complications including dislocation events, impingement or neurological complications were observed. Furthermore, no patient required revision surgery.
conclusionPrimary total hip arthroplasty with far proximal, non-anatomic socket positions is a safe and effective treatment option with excellent functional long-term results in severe dysplastic hip osteoarthritis.
