Figure 2

Absolute difference in adjusted probability of documentation of a nystagmus assessment when a template with a nystagmus item was used compared to when a template with a nystagmus item was not used. Error bars represent 95% confidence intervals. a Absolute difference for the multivariable model was calculated as follows: Adjusted probability of receiving a nystagmus assessment when a template with a nystagmus item is used MINUS adjusted probability of receiving a nystagmus assessment when a template with a nystagmus item is not used. Probabilities of nystagmus assessment was derived from a logistic regression model with nystagmus assessment as the dependent variable and the following independent variables: socio-demographic variables (age, gender, race-ethnicity, insurance status), hospital, type of dizziness symptom, dizziness presentation type, number of medical symptoms, number of other neurologic signs or symptoms, number of stroke risk factors, admission status, and nystagmus item template. Probabilities were calculated with all other variables in the model held constant at the population means. b Absolute difference for the propensity score analysis was calculated using nearest neighbor propensity score matching. First a propensity score was derived (see Additional file 1). Then, the propensity score was used for nearest neighbor matching to calculate the adjusted absolute difference in the probability of receiving the nystagmus assessment when a nystagmus item template was used compared to when a nystagmus item template was not used. Covariates used in the model were the following: socio-demographic variables (age, gender, race-ethnicity, insurance status), hospital, type of dizziness symptom, dizziness presentation type, number of medical symptoms, number of other neurologic signs or symptoms, number of stroke risk factors, admission status, and nystagmus item template.
