The study estimated the proportion of controls who were exposed to factors of interest (difficulty in educating children and fears and misconceptions of family members about BRAC health program) at 15%, based on an existing study of BRAC urban CHWs [18].
The total proportion of patients carrying one of these nsSNPs within this region of GRM1 was 0.8%, whereas the proportion of controls was 0.2% (t-test, P = 0.015).
The number of controls is n1, and cases n2, with N = n1+n2 and
The proportion of microinvasive cases with screening predating diagnosis was similar to the proportion of controls.
Methylation was also detected in a small proportion of controls (16%).
A larger proportion of controls had more than three births and were current smokers.
The proportion of controls moving into a lower risk category was 11.2 % for BCRAT, and 8.2 % for IBIS, while the proportion of controls moving into a higher risk category was 40.3 % for BCRAT and 33.5 % for IBIS.
The proportion of controls, who were mostly older, who had received the trivalent seasonal vaccine was higher than the proportion of controls who had received the monovalent vaccine (Table 1).
A higher proportion of controls than cases had both parents smoking, and control-mothers were more educated than case-mothers.
A higher proportion of controls than cases reported ERT use, whereas combined HRT use was more common among cases.
At the time of the study, a higher proportion of controls were alive compared to the cases.
