Article in JIMD reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02055118 (A Controlled, Randomized, Two-arm, Open-label, Assessor-blinded, Multicenter Study of Intrathecal Idursulfase-IT Administered in Conjunction With Elaprase® in Pediatric Patients With Hunter Syndrome and Early Cognitive Impairment), which is not on this map.

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.

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.

Abstract

Data from a phase 2/3, randomized, controlled, open-label, multicenter trial in children with neuronopathic mucopolysaccharidosis II (MPS II; Hunter syndrome) older than 3 years suggested a benefit of intrathecal idursulfase-IT on cognitive functioning in some patients. We describe a separate, parallel, open-label, single-arm, 52-week substudy of the same trial (NCT02055118) that investigated idursulfase-IT in children with MPS II younger than 3 years at enrollment and Bayley Scales of Infant and Toddler Development (BSID-III) quotient 55-85. This report describes a prespecified analysis of nine patients (aged 1.4-3.0 years) who had received 3-years' treatment with idursulfase-IT. BSID-III cognitive composite scores generally remained relatively stable over time. At the last available assessment, scores were "high average" (110;
