Persistent bone and joint disease despite current treatments for mucopolysaccharidosis types I, II, and VI: Data from a 10-year prospective study.
Observational study in Journal of inherited metabolic disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
The mucopolysaccharidosis (MPS) disorders have many potential new therapies on the horizon. Thus, historic control data on disease progression and variability are urgently needed. We conducted a 10-year prospective observational study of 55 children with MPS IH (N = 23), MPS IA (N = 10), non-neuronopathic MPS II (N = 13), and MPS VI (N = 9) to systematically evaluate bone and joint disease. Annual measurements included height, weight, and goniometry. Mixed effects modeling was used to evaluate changes over time. All participants had been treated with hematopoietic cell transplantation and/or enzyme replacement therapy. Height z-score decreased over time in MPS IH, MPS II, and MPS VI, but not MPS IA. Adult heights were 136 ± 10 cm in MPS IH, 161 ± 11 cm in MPS IA, 161 ± 14 cm in MPS II, and 128 ± 15 cm in MPS VI. Adult average BMI percentiles were high: 75 ± 30%ile in MPS IH, 71 ± 37%ile in MPS IA, 71 ± 25%ile in MPS II, and 60 ± 42%ile in MPS VI. Every participant had joint contractures of the shoulders, elbows, hips, and/or knees. Joint contractures remained stable over time. In conclusion, despite current treatments for MPS I, II, and VI, short stature and joint contractures persist. The elevation in average BMI may be related, in part, to physical inactivity due to the ongoing bone and joint disease. Data from this longitudinal historical control study may be used to expedite testing of experimental bone and joint directed therapies and to highlight the need for weight management as part of routine clinical care for patients with MPS.
