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

Background: To examine the association between acetabular cup positioning and functional outcomes, measured with Harris Hip Score (HHS), in IPI patients after THA. Methods: A literature search was conducted in PubMed, CENTRAL, Epistemonikos, and Embase up to November 30, 2024. A multilevel random-effects meta-analysis was performed with a restricted maximum likelihood heterogeneity estimator and Hartung-Knapp adjustment. Logistic regression on pooled data identified acetabular cup inclination and anteversion cut-offs associated with IPI, we performed logistic regression analysis on pooled data from the included studies. Results: Ultimately, 32 studies with overall 1755 patients were included. The non-IPI subgroup (mean: 91.5; confidence interval [CI]: 88.2-94.9; I Conclusions: Acetabular cup inclination ≤ 44.1° and anteversion ≥ 18.7° may lower IPI risk following THA. These findings represent a step toward optimizing acetabular cup positioning for a better patient outcome.
