Relative risk ratios for histologic types of demographic variables among cases with known histology
| Predictor variable | ADCA | Large cell | Small cell | Others | P-value (LR test) |
|---|---|---|---|---|---|
| Sex (ref. = Male) | 3.92 (3.31–4.65)a | 1.87 (1.22–2.86)a | 0.66 (0.39–1.11) | 9.11 (9.04–9.18)a | <0.001 |
| Age (year) | 0.98 (0.98–0.99)a | 1.00 (0.99–1.02) | 1.00 (0.98–1.01) | 0.96 (0.93–0.99)a | <0.001 |
| Religion (ref. = non-Muslim) | 0.98 (0.85–1.13) | 0.86 (0.50–1.47) | 0.93 (0.58–1.49) | 0.99 (0.97–1.01) | 0.907 |
| Other district (ref. = Muang) | 0.98 (0.96–1.00) | 0.62 (0.40–0.95) | 0.87 (0.56–1.35) | 0.99 (0.90–1.09) | 0.084 |
| Year of Diagnosis (ref. <=2000) | 2.26 (1.84–2.77)a | 0.77 (0.55–1.09)a | 1.72 (1.22–2.43)a | 1.01 (1.01–1.01)a | <0.001 |
These variables are from the multinomial logistic regression model using SCC as the reference group. Muang district is the old town of Songkhla so it is set as the reference district
aStatistically significant with p-value < 0.05. P-values from likelihood ratio test are given in the last column. LR test = likelihood ratio test
