Increased pituitary volumes in patients with Sanfilippo syndrome (mucopolysaccharidosis type 3, MPS III).

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
purposeTo evaluate apparent pituitary gland enlargement in patients with Sanfilippo syndrome observed at our institution.
methodsTwelve patients with Sanfilippo syndrome with brain MRI were studied. Anterior, posterior, and whole pituitary volumes were estimated using the prolate ellipsoid volume calculation method (π/6 × L × W × H). Convexity along the upper pituitary margin (Elster's grade) was also measured. These values were compared to two age- and sex-matched groups (normal controls and patients with Hurler syndrome) using one-way ANOVA followed by Tukey's post hoc analysis for multiple comparisons.
resultsIn the Sanfilippo cohort, the mean whole pituitary volume was 529.9 mm, the mean anterior pituitary volume was 333.4 mm, and the mean posterior pituitary volume was 59.1 mm with Elster's grade of 4.2. In the control cohort, the mean whole pituitary volume was 217.4 mm, the mean anterior pituitary volume was 154.8 mm, and the mean posterior pituitary volume was 28.4 mm with Elster's grade of 2.5. In the Hurler syndrome cohort, the mean whole pituitary volume was 310.0 mm, the mean anterior pituitary volume was 178.2 mm, and the mean posterior pituitary volume was 35.4 mm with Elster's grade of 3.5.
conclusionIn our cohort of patients with Sanfilippo syndrome, whole, anterior, and posterior pituitary volumes and degree of convexity along the upper pituitary border were all significantly greater than controls. The cause of these morphological changes is unclear, as is clinical correlation of the findings.
