Validation of a Novel Low-Cost Glaucoma Risk Calculator for Community-Based Screening in High-Risk Populations.
Article in Clinical ophthalmology (Auckland, N.Z.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Purpose: To assess the validity of a novel, low-cost glaucoma screening calculator in determining glaucoma risk in high-risk New York communities. Patients and Methods: This prognostic community-based study was conducted in New York City neighborhoods from 2022 to 2024 among participants aged 40 years and older. Glaucoma screenings were held at community gatherings including local fairs, senior citizen homes, places of worship, and in the lobby of medical offices. The screenings were conducted by trained non-physician medical personnel comprised medical students and medical assistants working under physician supervision. Participants' intraocular pressure (IOP) and central corneal thickness (CCT) were measured in both eyes with a handheld tonometer and pachymeter, respectively. Participants then completed a comprehensive eye exam by an ophthalmologist to confirm glaucoma status. Statistical analysis was completed using MedCalc version 22.023 (MedCalc Software Ltd. Ostend, Belgium) with 95% confidence intervals. Results: Of the 823 study participants, 716 (mean age 62.9 ± 11.9 years) were eligible to participate and completed the comprehensive follow-up exam. 68% identified as Black, 6.7% identified as Hispanic/Latino, and 52.5% identified as female. The Laroche glaucoma calculator had a sensitivity of 93.5% (CI 89.1-96.5%), specificity of 91.3% (CI 88.5-93.6%), positive predictive value of 80.5% (CI 75.7-84.6%), negative predictive value of 97.3% (CI 95.5-98.4%) and accuracy of 91.9% (CI 89.6-93.8%). Conclusion: The Laroche glaucoma calculator shows high sensitivity, specificity, positive predictive value, negative predictive value, and accuracy using affordable screening methods to determine glaucoma risk.
