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: Dual-mobility (DM) articulations are increasingly used in revision total hip arthroplasty (THA) to reduce instability, but their effectiveness in conjunction with jumbo cups is unclear. This study evaluated the risk of all-cause and instability-related re-revision when DM articulations were used with jumbo vs standard cups in revision THA. Methods: A retrospective review included 199 revision THA patients with DM articulations: 156 with regular cups and 43 with jumbo cups (≥62 mm for females, ≥66 mm for males). Exclusion criteria were cup-cage constructs, cemented DM liners in pre-existing cups, and tumor cases. The primary outcome was re-revision, with focus on instability. Student's Results: At a mean 4.6-year follow-up, re-revision rates were similar between groups (10.3% regular vs 11.6% jumbo, Conclusions: Our results demonstrate satisfactory midterm outcomes in both jumbo and regular cup patients implanted with DM systems. These findings demonstrate that the use of DM liners in jumbo cups does not portend increased risk of re-revision compared to use of DM in regular sized cups.
