The relation between corneal optical quality and clinical ocular surface manifestations in Chinese female with Sjogren's syndrome dry eye.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo evaluate the relation between corneal optical quality and ocular surface manifestations in Chinese female patients with Sjogren's syndrome dry eye (SSDE).
methodsCross-sectional study of female SSDE patients. Demographic information and ophthalmological and rheumatological indicators were collected. Ocular Surface Disease Index (OSDI) and Chinese Dry Eye Questionnaire (CDEQ), best-corrected visual acuity (BCVA), first and mean noninvasive tear break-up time (FNIBUT and MNIBUT), Schirmer I testing, Oxford Staining Score (OSS), meibomian gland loss (MGL), and optical quality were evaluated using generalized estimating equation (GEE) models. Multinomial logistics regression models and multiple linear regression models were employed to assess the correlations between dry eye indicators and corneal optical quality.
results27 SSDE patients (47 eyes), 9 Non-Sjögren's Syndrome dry eye patients (NSSDE, 14 eyes), and 23 normal controls (NC, 44 eyes) were included. More severe dry eye signs and poorer results of corneal optical qualities were found in Chinese female SSDE patients (all p < 0.05). More severe dry eye signs (CDEQ score, FNIBUT, MNIBUT, OSS, Schirmer I test, lipid layer distribution, and MGL) and poorer results of corneal optical qualities (angle α) were found in SSDE patients (all p < 0.05). In addition, there was a significant difference in astigmatism (posterior corneal surface astigmatism, and the types of astigmatism on the anterior and posterior surface of the cornea) between the groups (all p < 0.05).
conclusionsChinese females with DE, and particularly those with concurrent SS, demonstrated poorer ocular surface and corneal optical quality measures than those without DE.
