Bidirectional Causal Relationships between Corneal Biomechanics and Glaucoma or Intraocular Pressure.
Article in Ophthalmology science. 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
Objective: To investigate the bidirectional causal relationships between corneal biomechanics (corneal hysteresis [CH] and corneal resistance factor [CRF]) and glaucoma subtypes or intraocular pressure (IOP), and to evaluate the mediating role of IOP in these associations. Design: Bidirectional univariable 2-sample Mendelian randomization (MR), multivariable MR, and mediation MR study using genome-wide association study (GWAS) summary statistics. Subjects: Genetic data from large-scale GWAS cohorts of European ancestry, including individuals with measurements of CH/CRF, glaucoma subtypes (primary open-angle glaucoma [POAG], primary angle-closure glaucoma [PACG], normal-tension glaucoma [NTG], exfoliation glaucoma [XFG], juvenile open-angle glaucoma [JOAG], glaucoma suspect, neovascular glaucoma, secondary glaucoma, and other unspecified glaucoma), and glaucoma endophenotypes (IOP, retinal nerve fiber layer thickness, vertical cup-to-disc ratio). Methods: Bidirectional univariable 2-sample MR analyses were performed to assess the causal effects between CH/CRF and glaucoma subtypes. Multivariable MR and mediation analysis were used to evaluate the role of IOP. Inverse-variance weighted, weighted median, MR-Egger regression, and MR-Pleiotropy RESidual Sum and Outlier were used to evaluate the causal effects, pleiotropy, and heterogeneity. Main Outcome Measures: The primary outcomes included causal estimates (odds ratios or β-coefficients) for the associations between CH/CRF and glaucoma subtypes (POAG, PACG, NTG, XFG, JOAG, neovascular glaucoma, etc.) and the mediation effects of IOP. Secondary outcomes included relationships between glaucoma medication or surgery and CH/CRF. Results: Corneal hysteresis and CRF were causally associated with increased risks of total glaucoma and most subtypes, except for the protective effect of CH against neovascular glaucoma. Both CH and CRF elevated IOP. Adjusting for IOP attenuated CH/CRF-glaucoma associations. Glaucoma inversely affected CH but positively influenced CRF. Glaucoma surgery reduced CH and CRF. Conclusions: This study suggests that CH and CRF are risk factors for glaucoma and its subtypes, with IOP playing a mediating role in this relationship. These findings highlight the role of corneal biomechanics in glaucoma pathophysiology and clinical management.
