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
Introduction: This study examined the extent of provider consolidation across the outpatient sector overall and analyzed variation by ownership type, including vertically integrated health systems and large corporate owners. Methods: Using data from the Agency for Healthcare Research and Quality (AHRQ) Compendium of US Health Systems and the IQVIA OneKey Database, we analyzed changes from 2020 to 2023 in the number and share of outpatient sites and outpatient physicians affiliated with health systems and corporate owners, overall and variation by profit status, owner size, and geographic scope. Results: The number of outpatient physicians classified as independent or other type decreased by 34 770 (-7.0 percentage points) from 2020 to 2023. Outpatient consolidation into health systems and corporate owners was relatively high in 2020 and increased modestly from 2020 to 2023. Data validation identified some risk of misclassification of parent ownership status with a potential to bias upwards the prevalence of corporate ownership. Conclusion: Our findings on changes in outpatient consolidation provide a baseline for tracking the growth in parent ownership across the outpatient sector overall and highlight the critical need for more accurate and standardized data on ownership and organization to address key policy issues related to competition, antitrust, and quality impacts.
