From: Pre-diagnostic cruciferous vegetables intake and lung cancer survival among Chinese women
Multivariable-adjusted lung cancer-specific survival curves of patients (n = 547) with lung cancer by pre-diagnostic intake of cruciferous vegetables, estimated from a stratified proportional hazards model (stratified on birth year and adjusted for age at diagnosis, body mass index, tea drinking, cigarette smoking, intakes of energy, fruit and non-cruciferous vegetables) by using a direct adjustment method36. The green line indicates the Q1 (lowest) of intake, the blue line indicates the Q2, the gold line indicates the Q3 and the red line indicates the Q4 of intake (highest).
