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

Healthcare firms regularly seek outside capital; yet, we have an incomplete understanding of external investor influence on provider behavior. We investigate the effects of private equity investment, divestment, and an initial public offering (IPO) on ambulatory surgery centers (ASCs). Throughput is unchanged while charges grow by up to 50% for the same service mix. Affected ASCs witness declines in privately insured cases and rely more on Medicare business. Private equity increases physician ASC ownership stakes, and both simultaneously divest when the ASC is sold. Our findings appear more consistent with private equity influencing the financing of ASCs, rather than treatment approaches.
