Estimates of the Association between Caregivers’ Low Health Literacy (Defined as NVS Score of less than 2) and the Incidence of Children’s Medicaid Enrollment Gaps, Overall and Stratified by Educational Attainment, among the COHL Study Follow-up Cohort in North Carolina, during the Study Period (A)

Note. NVS = Newest Vital Sign; COHL = Carolina Oral Health Literacy; IRR = Incidence Rate Ratio; CI = Confidence Interval; GED = General Educational Development. The sample size was n = 1208.
aVariable selection was based on a backward hierarchical procedure starting from a full model and a P<.2 criterion; caregivers’ race, age and general health were included a priori in the models; time at risk for a gap was considered time (months) of Medicaid enrollment.
