*Values in bold are considered statistically significant, RRR = relative risk ratio
The reference group of the nominal logistic regression model used a combination of responses of Observations, Doppler and Pressure measurement
^aBachelor or equivalent degree was used as the reference category for education level
^bPrivate practitioners were used as the reference category for work setting
