Does State-Level Nurse Practitioner Scope-of-Practice Policy Affect Access to Care?
Synthesis in Western journal of nursing research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
There is heated debate surrounding policy reform granting full state-level nurse practitioner (NP) scope of practice (SOP) in all U.S. states. NP SOP policy is argued to impact access to care; however, a synthesis of empirical studies assessing this relationship has yet to be performed. Our study fills this critical gap by systematically reviewing studies that examine this relationship. We apply Aday and Andersen's Access Framework to operationalize access to care. We also use this framework to map components of access to care that may relate to NP SOP through concepts identified in this review. Our findings suggest that full state-level NP SOP policy is associated with increases in various components of access to care, but additional work is needed to evaluate causality and underlying mechanisms behind this policy's effect on access. This work is necessary to align research, practice, and policy efforts surrounding NP SOP with healthcare accessibility.
