Table 3: Distribution of alcohol types in the study. The GFHC was associated with a marginal risk of OSCC with an OR of 1.095 (95% CI 0.953-1.259), without significance (\(p=0.199\)) (Table 5). The FHHNC showed a notable associated risk with an OR of 1.871 (95% CI 0.902-3.882), without significance (\(p=0.092\)). The FDFH had an OR of 1.154 (95% CI 0.949-1.403), without significance (\(p=0.152\)). The SDFH had an OR of 1.039 (95% CI 0.853-1.266), without significance (\(p=0.706\)). The distribution of patients according to the number of affected relatives are presented in Table 6. TG showed relatively more patients with increased number of relatives affected by cancer. \begin{table}
