Table 3 legend: Column percentages may not equal 100% due to rounding. The p-value is based on STATA’s design-based Rao–Scott F-test and tests for a potential association between shiftwork status and the respective variable. c = Estimate considered unreliable per NHCS analytic guidelines (based on STATA’s postestimation command “kg_nchs”).
