1 · What the graph read from it

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.

2 · The registry

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 identify temporal and geographic trends in private equity (PE)-backed acquisitions of ophthalmology and optometry practices in the United States from 2012 to 2021. Methods: In this cross-sectional time series, acquisition data from 10/21/2019 to 9/1/2021 and previously published data from 1/1/2012 to 10/20/2019 were analyzed. Acquisition data were compiled from 6 financial databases, 5 industry news outlets, and publicly available press releases. Linear regression models were used to compare rates of acquisition. Outcomes included number of total acquisitions, practice type, locations, provider details, and geographic footprint. Results: A total of 245 practices associated with 614 clinical locations and 948 ophthalmologists or optometrists were acquired by 30 PE-backed platform companies between 10/21/2019 and 9/1/2021. Of 30 platform companies, 18 were new vis-à-vis our prior study. Of these acquisitions, 127 were comprehensive practices, 29 were retina practices, and 89 were optometry practices. From 2012 to 2021, monthly acquisitions increased by 0.947 acquisitions per year ( Conclusions: PE acquisitions increased during the period 2012-2021 as companies continue to utilize regionally focused strategies for acquisitions.
