Stability of hip hemiarthroplasties.
Synthesis in International orthopaedics, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 38 papers, 2 of them syntheses that pooled 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.
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
It has been stated in the literature that a bipolar hemiarthroplasty has a lower risk of dislocation compared to a unipolar hemiarthroplasty. As this statement has not been substantiated we undertook a systematic review of the literature of published articles from the last 40 years. In addition we used our own database of hip fractures. One hundred and thirty-three published articles were included in the review to give a total of 23,107 cases. The overall dislocation rate for all types of hemiarthroplasty was 791/23,107 (3.4%). An increased risk of dislocation was associated with a posterior surgical approach and the use of a cemented prosthesis. After adjustment for surgical approach and the use of cement there was no difference in risk of dislocation between unipolar and bipolar hemiarthroplasties. There was an increased risk of open reduction for a bipolar hemiarthroplasty.
