aA univariate risk factor analysis was performed to determine factors associated with undervaccination in high- and low-coverage areas using Confidence Intervals of 95%. Groups with incomplete schedules were placed in the “positive outcome” column, while those with complete schedules were placed in the “negative outcome” column. Statistically significant values (p < 0.05) are bolded.
bUnder this category, seven cases marked as “other” were excluded.
cThe category “single” includes participants who indicated being single, divorced, or widowed.
dParticipants were asked if they had multiple children aged 0–5 years. Categories correspond to the birth order of only those children aged 0–5 years.
