    Article Title: Selection Bias Due to Parity-conditioning in Studies of Time Trends in Fertility
    Article Snippet: .. We considered truncation bias by restricting time-to-pregnancy starting dates between 1 July 1972 and 31 December 1981. the data on time to pregnancy by continuous maternal year of birth were analyzed using discrete proportional hazards regression (SaS PrOc PHreg procedure with exact handling of ties) providing fecundability density ratios (FDrs). all analyses were carried out using the Statistical analysis System 9.4 program (SaS institute, cary, nc). no trend in fertility was seen in the age-adjusted analysis of birth cohort effect, which included all the women (n = 950; FDr = 1.00 [95% confidence interval (ci) = 0.98–1.02]). a subset analysis of nulliparous women (n = 338) induced a strong trend toward an increase in fertility for each increasing year of birth (FDr = 1.04 [1.00–1.07]). thus, restriction to nulliparous women seems to have caused a selection bias in a setting not particularly designed for studying trends in fertility. ..
