Descriptive statistics are available in Table Main effect of intervention on URE in social media. State legislators receiving the intervention from the RPC produced 24% more COVID-related social media posts with URE than those not in the intervention group, controlling for the effect of state professionalism on zero-inflationDescriptive statisticsIntervention effect modeled with zero-inflated negative binomial regressionsThis is a zero-inflated model, such that the model simultaneously conducts a logistic regression to determine predictors of whether the legislator created any posts with URE (0 vs 1 + ; i.e., the zero inflation), and a negative binomial regression to determine predictors of how frequently the legislator created posts with URE among those with more than 0 posts (the count model). We modeled the inflation with the index of state professionalism and their experimental condition (Intervention), and the count with just the experimental condition. The columns under “Logistic/inflation model” report the OR (odds ratio) and associated numbers for those predictors, and the columns under “Count model” report the IRR (incident rate ratio) for the intervention indicatorOverall URE is the count of social media posts that had any of the following eight URE type categories that follow. Control group was the reference in these analysesThe Squire Index was included in every model conducted and was a significant predictor of zero inflation for all models (Secondary analyses (Fig. Secondary analyses: intervention effect on URE categories in social media. The relationship between the intervention and URE in social media products was driven primarily by the Data/analytics and Conceptual sub-categories. State legislators in the intervention group produced 67% more COVID-related social media posts with URE falling in the Data/analytics category than those not receiving the intervention, controlling for the effect of state professionalism on inflation. Legislators in the intervention group produced 28% more COVID-related social media posts with URE in the Conceptual category than those not receiving the intervention, controlling for the effect of state professionalism on inflation. Legislators in the control group produced 69% more social media posts with URE in the Knowledge Generation category
