From symbolism to substance: evaluating state disclosure laws and the case for federal oversight.

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
Pharmaceutical payments to physicians have long raised concerns about conflicts of interest and rising healthcare costs. While the Physician Payments Sunshine Act (PPSA) established federal transparency standards in 2013, several states had already enacted their own disclosure laws. This study evaluates the hypothesis that individual state policies varied in effectiveness at shaping corporate payment strategies. Specifically, we examined four state policies, Massachusetts (MA), Maine (ME), Minnesota (MN), and West Virginia (WV), using a difference-in-differences design, comparing the outcomes with matched control states before and after PPSA implementation. We analyzed meals and travel payments from four major pharmaceutical companies using ProPublica's Dollars for Docs (2012-2013) and Centers for Medicare & Medicaid Services' Open Payments (2014-2015) data. Results indicate that MA's comprehensive policy, featuring strict reporting requirements, public accessibility, and enforcement, yielded a significant 44% decline in travel payments. In contrast, ME, MN, and WV's policies showed negligible impacts. These findings suggest that disclosure laws exert real influence only when they are comprehensive, transparent, and backed by enforcement. This underscores the critical role of policy structure in addressing conflicts of interest and points to ways the PPSA framework could be strengthened. Based on our findings, we suggest that other nations could strengthen their systems by adopting centralized and standardized reporting systems, similar to the PPSA.
