1 · What the graph read from 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.

Abstract

X-linked hypophosphatemia (XLH) is a rare genetic condition in which excess fibroblast growth factor 23 causes renal phosphate wasting, leading to skeletal morbidities. Patients experience musculoskeletal pain, stiffness, and fatigue, with impaired physical function and health-related quality of life (HRQL). Burosumab has been available in France for the treatment of XLH since 2021; European treatment guidelines suggest use in adults with pseudofractures or with insufficient response and/or intolerance to oral phosphate supplements and active vitamin D. The International XLH Registry is collecting long-term observational data in a real-world setting from patients with XLH. Here, we report data from French adults from their first completion of the Short-Form 36 (SF-36) version 2 health survey, a measure of health-related quality of life. The analysis used data from 123 adults who completed the survey at least once (73% women; mean age at completion 42.5 yr [SD 13.4]; mean age at diagnosis 8.8 [12.6] yr). Group mean T-scores in the current International XLH Registry sample were <47 on all SF-36 scale and summary scores, indicating impaired functioning. Physical and mental component summary scores were similar (43.0 [SD 9.1] vs 43.4 [11.3]). Worse physical component summary scores were significantly related to older age (
