Medicare Payment to Service Volume Elasticities for Glaucoma Procedures From 2013 to 2021.

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: Glaucoma is a leading cause of irreversible blindness, and Medicare payments influence access to and utilization of glaucoma procedures. This study examines the relationship between Medicare payments and service volumes for glaucoma procedures. Methods: This retrospective longitudinal study used Medicare Part B National Summary Data Files from the Centers for Medicare and Medicaid Services (CMS). Data for glaucoma procedures from 2013 to 2021 with at least five years of available data were analyzed. The dataset included service volumes, average payments, total practicing ophthalmologists, and Medicare Part B beneficiary trends across the United States. The relationship between Medicare payments and service volumes was quantified using payment-volume elasticities, calculated as the percentage change in procedural volume per 1% change in Medicare reimbursement. Results: Twenty procedures were evaluated. Minimally invasive glaucoma surgeries (MIGS) exhibited the greatest sensitivity, with a payment-volume elasticity of 4.67% ( Conclusions: A significant relationship between Medicare payment adjustments and the utilization of glaucoma procedures was observed, with potential implications for access and care delivery. MIGS demonstrated the highest sensitivity to payment changes, suggesting that reimbursement policies could influence the adoption and availability of these surgeries beyond clinical decision-making.
