^aLogistic regression analysis was used to determine if any of the surveyed respondent characteristics could contribute to the odds of diagnosing CP in each of the 4 hypothetical case scenarios (separate logistic regression model for each scenario).

^bORs are indicated for each respondent characteristic relative to the indicated reference value.

^cOnly the overall logistic regression model for scenario 4 significantly predicted the likelihood that a respondent would diagnose CP on the basis of the indicated respondent demographics (χ² statistic, P = .008). Of the examined demographics, only the respondent’s medical specialty was a significant predictor of whether a respondent would diagnose CP in scenario 4, with neurologists almost 5 times more likely to diagnose CP than pediatricians.

^dThese ORs are adjusted for all of the indicated respondent characteristics for each scenario.

^*P = .017 (Wald test).
