1234p for trend
Conditional logistic regression analyses were matched for age, sex, date of blood sampling, fasting status, and time of last food consumption and further adjusted for smoking status.
IGF-I, insulin-like growth factor 1; IGFBP, IGF binding protein; OR, odds ratio; CI, confidence interval.
