Risk of acetabular protrusion is low in rheumatoid arthritis patients treated with bipolar hemiarthroplasty for displaced femoral neck fractures without rheumatoid change in hip joints.

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
objectivesThe aim of this study was to analyze the radiological outcomes of bipolar hemiarthroplasty after displaced femoral neck fractures of non-arthritic hip joints in rheumatoid arthritis patients.
methodsWe retrospectively investigated 25 hip joints in 23 rheumatoid arthritis patients who underwent bipolar hemiarthroplasty for displaced femoral neck fracture of non-arthritic hip joints. All patients were female with an average age of 69.8 years (range 51-83 years). Mean follow-up duration was 8.4 years (range 5-12 years). Radiographs taken immediately, 1 year after surgery and most recently, were collected for each case. Radiographic measurement of the migration distance of the outer-head prosthesis in the direction of vertical, horizontal and medial to Köhler's line was undertaken at 1 year after surgery and most recently.
resultsNo patients had hip-related pain after surgery. No case indicated apparent central migration and >3-mm migration of the hemisphere in each direction. There was no significant change in migration distance between evaluation at 1 year after surgery and most recently.
conclusionsWe conclude that risk of acetabular protrusion appears to be low in patients of rheumatoid arthritis treated with bipolar hemiarthroplasty for displaced femoral neck fractures of non-arthritic hip joints in the medium term.
