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
This report describes a rare case of early nontraumatic periprosthetic femoral fracture following total hip arthroplasty. The patient was a 74-year-old woman with osteoarthritis of the hip who underwent left total hip arthroplasty via a posterior approach using a tapered, rectangular, cementless femoral stem. The patient progressed well through early rehabilitation and was ambulating independently by postoperative Day 8. However, on postoperative Day 9, she experienced sudden-onset thigh pain and was unable to bear weight while ascending stairs. Radiographs demonstrated a short oblique fracture of the left femur that was located distal to the stem tip and classified as a Vancouver type C (postoperative) fracture. Open reduction and internal fixation were performed using a locking plate in conjunction with cables and screws. At the 2-year follow-up, the patient had regained her ability to ambulate independently, and radiographs confirmed successful bone union. Finite element analysis suggested that concentration of stress around the tip of the stem as a result of flexed stem alignment, together with stair climbing, may have contributed to the periprosthetic femoral fracture. Caution is warranted when inserting a femoral stem in a flexed position because of an increased risk of periprosthetic femoral fracture.
