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

Dual mobility (DM) constructs reduce dislocation risk in total hip arthroplasty. The Trident II system accepts a cobalt-chromium liner to create a DM bearing. However, dissimilar metal at the cup-liner interface raises concerns for corrosion. This case series describes six cementless primary Trident II DM total hip arthroplasty patients who experienced gradual onset of hip pain with low-grade inflammatory symptoms and elevated serum cobalt. All patients underwent revision surgery for metallic debris reaction. Preoperative magnetic resonance imaging revealed local tissue reaction, and intraoperative findings confirmed corrosion at the cup-liner interface. Surviellance through serum metal ion testing and magnetic resonance imaging may prevent soft tissue damage and facilitate timely revision. As DM systems evolve, further investigation is warranted to evaluate safety.
