Efficacy of early haematopoietic stem cell transplantation versus enzyme replacement therapy on neurological progression in severe Hunter syndrome: Case report of siblings and literature review.
Article in Molecular genetics and metabolism reports, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Hunter syndrome is a neurodegenerative lysosomal storage disorder with limited treatment options to halt the progressive neurocognitive decline. Whilst Intravenous enzyme replacement therapy (ERT) does not cross the blood brain barrier; Intrathecal ERT, in clinical studies, did not demonstrate significant effect on cognition, despite having better CNS delivery. Hematopoietic stem cell transplantation (HSCT) has the potential to treat CNS disease. We reviewed the literature and outline our experience of treating two siblings with severe Hunter syndrome: 'Sibling A' with intravenous and intrathecal ERT and 'Sibling B' with Early HSCT. A literature review identified 8 articles reporting on the comparative efficacy of both treatments. Our clinical outcomes indicate that Sibling B performed better than Sibling A in relation to early developmental milestones as well as neurocognition, activities of daily living, quality of life and neurophysiological outcomes in mid childhood. Sibling A's developmental trajectory fell within the extremely low range and Sibling B's development trajectory fell within the low-average to average range. This suggests HSCT had a disease modifying effect and highlights the efficacy of early HSCT in moderating the CNS progression in Hunter syndrome. Long term follow up is needed to elucidate the efficacy of HSCT on neurological progression.
