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
Introduction: Ankylosing spondylitis (AS) is a chronic inflammatory disease that can lead to progressive joint ankylosis, most commonly affecting the spine and hips. Severe cases may result in functional autoarthrodesis of multiple lower extremity joints, significantly impairing mobility and quality of life. Although total hip and knee arthroplasty are well-described individually in AS, management of simultaneous multi-joint ankylosis in extreme flexion deformity is rarely reported. Case Report: We report the case of a 23-year-old male with advanced AS resulting in bilateral hip and knee autoarthrodesis fixed in severe flexion, rendering him wheelchair-bound for 3 years. He underwent four staged arthroplasty procedures over the course of 1 year, consisting of bilateral total hip arthroplasties followed by bilateral total knee arthroplasties, with approximately 8-week intervals between procedures. Significant intraoperative challenges included absent normal joint anatomy, extreme flexion deformities (hips 80-85° and knees 70-75°), and complex patient positioning. The hips were addressed through an anterolateral approach, and the knees through a medial parapatellar approach with adjunctive osteotomies and soft-tissue releases as needed. Postoperatively, the patient underwent intensive rehabilitation and subsequent manipulation under anesthesia to improve the range of motion. Functional outcome measures demonstrated substantial improvement, with hip disability and osteoarthritis outcome score increasing from 6.9 to 61.3, Harris Hip Score from 15 to 63, and knee injury and osteoarthritis outcome score from 9 to 41. Conclusion: Staged total hip and knee arthroplasty in severe AS with autoarthrodesis can result in meaningful functional recovery. Careful pre-operative planning, staged reconstruction, and tailored rehabilitation are essential to optimize outcomes and minimize complications in these complex cases.
