Association of Vitamin D deficiency with primary glaucoma among Saudi population - A pilot study.

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
purposeGlaucoma is a complex multifactorial disorder that is influenced by various systemic conditions. Several studies investigated the association between systemic factors such as Vitamin D deficiency for glaucoma development and reported contradicted findings. The aim of this study was to assess Vitamin D levels in glaucomatous Saudi subjects and its association with cup/disc ratio in primary open- and closed-angle glaucoma.
methodsThis was a pilot study that included subjects aged 41-78 years from both genders recruited from a tertiary hospital, Riyadh city, Kingdom of Saudi Arabia. Subjects were divided into three groups: Group 1: subjects with primary open-angle glaucoma (POAG), Group 2: subjects with primary angle-closure glaucoma (PACG), and Group 3: control subjects. All participants underwent detailed ophthalmic examinations including visual acuity, intraocular pressure measurement (IOP), gonioscopy, and fundus examinations. In addition, blood samples were collected from glaucoma patients and controls to measure the serum 25-hydroxyvitamin D levels.
resultsA total of 75 subjects were included in this study. Measurement of IOP was within the range of 9-27 for all subjects. Mean serum 25-hydroxyvitamin D levels were 72.58 ± 31.79, 69.20 ± 24.24, and 67.14 ± 29.02 in Groups 1, 2, and 3, respectively. There were insignificant differences in Vitamin D levels among the three groups (
conclusionNo association was found between Vitamin D deficiency and both POAG and PACG among Saudi population despite low serum level of Vitamin D in glaucomatous and control subjects. This study suggested that Vitamin D level may not contribute in augmenting the severity and progression of glaucoma.
