Table 3 Relative risk ratios for histologic types of demographic variables among cases with known histology

From: The use of a multiple imputation method to investigate the trends in Histologic types of lung cancer in Songkhla province, Thailand, 1989–2013

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
  1. 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
  2. aStatistically significant with p-value < 0.05. P-values from likelihood ratio test are given in the last column. LR test = likelihood ratio test
