Parent-of-origin effect in multiple sclerosis: observations in half-siblings Summary Multiple sclerosis is a complex trait in which occurrence rates in offspring are 20–50-fold greater than in the general population. Parent-of-orig... GC Ebers and AD Sadovnick and DA Dyment and IML Yee and...
Sex ratio of multiple sclerosis in Canada: a longitudinal study Incidence of multiple sclerosis is thought to be increasing, but this notion has been difficult to substantiate. In a longitudinal population-based dataset... SM Orton,BM Herrera,IM Yee,... - 《Lancet Neurology》 被引量: 1440发表...
To examine time trends and sex patterns in Hodgkin's disease incidence in Canada, from 1970 through 1995. In addition to analyses of the secular trends and sex ratio in incidence rates, age-period-cohort models were fitted to estimate the effects on the trends. Age-specific male/female incide...
In a longitudinal population-based dataset of patients with multiple sclerosis (MS), we have previously observed a substantial increase in the female to male sex ratio in Canada over the last 50 years. Here, we aimed to determine whether this change in sex ratio is related to the clinical co...
In Europe the female-to-male ratio varies from 1.1 to 3.4. A recent study from Canada has reported a significant increase, with time, in female-to-male ratio in multiple sclerosis over the last 100 years.Objective: The aim of this study was to analyse any change in sex ratio in ...

We evaluated patterns in the secondary sex ratio (SSR, number of male per 100 female births) according to ethnicity in Québec, Canada. We performed a population-based retrospective analysis of live and still births in urban Québec, 1981-2004 (N = 1,612,614 live births). Outcomes included...

The purpose of this study was to verify whether any changes in sex ratio might occur in soft-shell clams (Mya arenaria) located in an intertidal harbor zone located at the mouth of the Saguenay Fjord in the Saint Lawrence estuary (Baie Sainte-Catherine (BSC), Que´bec, Canada) likely to...
In no year did offspring sex ratio deviate significantly from 50:50, regardless of the sex ratio of breeding adults. Offspring sex ratio did not vary as a function of the timing of breeding, maternal or paternal age, or parental mating status (monogamy vs. polygamy). Overall, our data ...
