The impact of vertical integration on health care delivery and costs: Evidence from physician-pharmacy integration.
Article in Journal of health economics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Vertical integration among health care providers is an increasingly common feature of U.S. health care. This study investigates the impact of vertical integration in the context of oncology practices launching in-house pharmacies dispensing high-cost oral cancer treatments using a stacked event study design. I find physician-pharmacy integration lowers point-of-sale drug prices paid by plans due to 1.0% lower prices at in-house pharmacies. I also find physician-pharmacy integration increases the number of patients filling new prescriptions by 6.2% and reduces time-to-fill for new prescriptions requiring prior authorization. These effects may arise because in-house pharmacies individually have limited bargaining power and because vertical integration decreases coordination costs, reflected by faster prior authorization.
