Macular ganglion cell complex layer thickness measured with spectral-domain OCT in a large population-based cohort study.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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 establish the normal GCC thickness profile in the general population using SD-OCT in different macular sectors. Determining the systemic and ophthalmic factors associated with GCC thickness and further identifying the potential risk factors were the secondary objectives.
methodsParticipants in the population-based cohort study had to be at least thirty years old. Every participant had a routine ophthalmological examination. Using SD-OCT, the GCC thickness was determined. To assess the relationship between GCC thickness and systemic and ocular characteristics, mixed linear models were used. R V.4.1.1 was the statistical analysis program utilized.
resultsTwo thousand four hundred ninety subjects, average age 56.60 ± 10.39 years, were collected in this analysis. GCC average thickness measured was 95.57 ± 7.47 μm. The GCC thickness of the superior (95.46 ± 7.87 μm) was the thinnest, and the inferior subfield (95.68 ± 7.66 μm) was thickest. In the multivariate regression analysis, a thinner GCC was majorly linked to being older (P < 0.001), current smoking (P < 0.001), no diabetes (P = 0.014), and a larger vertical cup disc ratio (VCDR) (P < 0.001). When the data was divided by age, a thinner GCC was also connected to female (P < 0.001), current smoking (P = 0.006), having high systolic blood pressure (SBP) (P = 0.002), lower low-density lipoprotein (LDL) (P = 0.002), higher triglycerides (TG) (P = 0.029), higher best corrected visual acuity (BCVA) (P < 0.001), and a larger vertical cup disc ratio (VCDR) (P = 0.002). Stratified by axial length (AL), a thinner GCC was associated with advanced age (P < 0.001), female (P = 0.005), and a larger VCDR (P = 0.001).
conclusionsOur study provides benchmarks for GCC thickness, distribution, and linked ocular and systemic factors among middle-aged individuals in rural China, emphasizing the strong correlation between GCC thickness and multiple ocular and systemic variables. Additionally, our findings underscore the importance of establishing global normative databases to address ethnic variations in GCC thickness and the distinctiveness of related ocular and systemic factors.
