Effects of head posture on intraocular pressure and heart rate of human beings.
Article in Oman journal of ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundThe study analyzed the association of head posture on intraocular pressure (IOP). The study aimed to evaluate and measure the changes in IOP and heart rate (HR) of human beings on head-down posture. The study included 105 patients at the department of ophthalmology of a tertiary care center in India. SUBJECTS AND
methodsPatients underwent applanation tonometry and HR variability (HRV) analysis before and after 20 min of head-down posture (approximately 20°). The IOP and HRV were measured. STATISTICAL ANALYSIS USED: The statistical methods of Paired
resultsAfter 20 min of the 20° head-down position, an increase in IOP was significant from 15.0 ± 2.0 mmHg to 18.0 ± 2.3 mmHg (
conclusionsThese outcomes presented the first evidence of the activation of the parasympathetic nervous system in the head-down position which might cause decreased HR and the collapse of Schlemm's canal lumen, which in turn leads to the increased IOP.
