In our specification, the public sector and contractor dummy variables equal zero if the universal mandate variable equals one.
For states that did not enact a mandate, this variable was constant.
In most countries, access to healthcare varies according to socioeconomic and geographic variables, mandating efforts to decrease health disparities [ 7, 8].
Given variable mandate and resources for implementation, it was considered the most feasible approach, and therefore most likely to have impact due to potentially broad use.
Finally, small number of patients in our cohort relative to the studied variables mandates external validation of our prediction model before it can be used in clinical practice.
Given variable mandate and resources, international guideline developers thought that including information within guidelines that would help users to implement them was the most feasible approach, and more likely to promote guideline use due to potentially broad application.
Given variable mandate and resources for guideline implementation, it was considered the most feasible and cost-effective approach, and therefore most likely to have impact due to potentially broad use.
While implementation approaches and strategies need not be standardized across organizations, the findings suggest that even if we learn more about how to tailor implementation strategies to enhance their effectiveness, it is not clear who would apply these strategies, and how, given variable mandates, lack of frameworks to guide implementation decision making, and limited resources.
This situation mandates proper selection of independent variables for the infill drilling recovery model.
In particular, we have experimented with a linear measure of 'years to enactment of mandate' as well as with indicator variables for 'future mandate' together with indicator dummies for 1 3 or 1 5 years to the enactment of the mandates (these results are not displayed for the sake of brevity).
