Evaluation of optic nerve head morphology of small optic discs in healthy eyes with different optical coherence tomography parameters.

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
BACKGROUND/
aimTo compare Bruch's Membrane Opening- Minimum Rim Width (BMO-MRW), peripapillary retinal nerve fibre layer (pRNFL) thickness at different peripapillary diameters, and ganglion cell layer- inner plexiform layer (GCL-IPL) thickness between in eyes with small optic discs and normal discs.
methodIn this cross-sectional study, we selected healthy eyes. The patients were divided into two groups: the first group consisted of those with a disc area smaller than 1.60 mm² (Small disc group, 92 patients), and the second group included those with a disc area between 1.60 mm² and 2.50 mm² (Normal disc group, 71 patients). Spectralis OCT (Heidelberg Engineering, Inc., Heidelberg, Germany) was used to measure BMO-MRW and pRNFL thickness at three different diameters (3.5 mm, 4.1 mm, and 4.7 mm) using the Glaucoma Module Premium Edition (GMPE) software version 6.0. The thickness of GCL-IPL and pRNFL at a diameter of 3.4 mm were measured using Cirrus OCT (Carl Zeiss Meditec, Dublin, CA, USA).
resultsIn the small disc group, the disc area, rim area, and cup/disc ratio were smaller compared to the normal disc group (p < 0.05 for each). In the small disc and normal disc groups, pRNFL thickness at each three diameters (3.5 mm, 4.1 mm, and 4.7 mm) measured by Spectralis OCT were similar in all quadrants (superior temporal, superior nasal, nasal, inferonasal, inferotemporal, and temporal) and GCL-IPL (average, minimum) and pRNFL thickness measured with Cirrus OCT were similar in all quadrants (superior, nasal, inferior, and temporal). However, BMO-MRW measurements in all quadrants were larger in the small disc group (p < 0.05 for all).
conclusionRNFL and GCL-IPL measurements were similar in all quadrants in both group. However, BMO-MRW measurements were higher in all quadrants in the small disc groups.
