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
introductionPolyethylene wear is known to be a major cause of long-term failure after primary hip arthroplasty which results in the activation of an innate immune response with subsequent osteolysis and component loosening. However, polyethylene wear in hip arthroplasty may be asymptomatic for a long time and following massive, eccentric abrasion of the cup with subluxation of the femoral head after fully polyethylene wear has not yet been described. Hereby, we present a case of rapid progressive eccentric wear of the acetabular cup after complete polyethylene liner abrasion in a ceramic-on-polyethylene bearing. CASE REPORT: A 80-year-old-lady presented on our emergency department with a subluxated hip arthroplasty on the right side implanted 30 years ago. The X-ray showed a Zweymüller stem combined with a Gartenmann cup and a ceramic head with excessive eccentric wear of the acetabular cup with razor blade sharp edges after fully polyethylene liner abrasion.
conclusionProgressive eccentric wear of the acetabular cup after fully polyethylene liner abrasion in ceramic-on-polyethylene bearings in hip arthroplasty may be asymptomatic for a long time but may progress rapidly. To prevent patients from extensive revision surgery and the revision surgeon from serious injury due to intraoperatively findings such as razor blade sharp edges, routine long-term follow-up radiographic evaluation is crucial.
