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.

Abstract
Significance: Accurate measurement of ocular surface deformation under intraocular pressure (IOP) is essential for understanding eye biomechanics and the progression of pressure-related diseases such as glaucoma. However, existing imaging techniques often involve trade-offs among spatial resolution, system complexity, and the ability to capture full-field three-dimensional (3D) deformation on highly curved, compliant tissues. Aim: We investigate the feasibility of a noncontact measurement framework that combines fringe projection profilometry (FPP) and two-dimensional digital image correlation (2D DIC) to recover full-field 3D displacement and strain on the ocular surface during pressurization. Approach: An Results: The proposed framework was able to capture the evolving deformation of the ocular surface, revealing spatially heterogeneous displacement and strain patterns. Localized regions of elevated strain were consistently observed, whereas the deformation fields exhibited smooth temporal progression across loading stages. The recovered strain distributions aligned with expected biomechanical behavior of the ocular structure, suggesting the capability of the method to resolve meaningful deformation features on a curved, compliant surface. Conclusions: The combined FPP-DIC framework indicates potential as a viable approach for measuring dense 3D displacement and strain on the ocular surface. This feasibility study establishes the potential of structured-light-based methods for ocular biomechanics and lays the foundation for future quantitative validation and
