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

We study the introduction of reference pricing to the California Public Employees' Retirement System. Reference pricing changes the relative price of using a hospital versus an ambulatory surgery center (ASC) for patients receiving a colonoscopy, leading to as good as random variation in patients' use of ASCs. We find a 10 percentage point increase in the share of patients using an ASC, leading to a $2300 to $1700 reduction in prices paid for patients who switch to ASCs. Our results suggest that the use of ASCs has a causal effect on prices paid and has no negative effect on patient health outcomes.
