Low Fear:

n = 9 patients not included in mother’s age, n = 1 patient did not have information for total injections or visits, n = 1 patient did not include ethnicity, n= 2 patients did not include race

Middle Quartiles:

n = 19 patients did not include mother’s age, n = 1 patient did not include mother’s highest education, n = 1 patient did not include race, n = 1 patient did not include ethnicity

High Fear:

n = 9 patients not included in mother’s age, n = 1 patient did not include race
