Abstract: The monthly distribution of MS patients' births (N= 965) was compared with that of the Sicilian population (N= 5,608,307). The distribution of births among MS patients compared with the general population was not different when tested by the chi2 statistic (P> 0.25). The Hewitt's non-parametric test for seasonality showed an excess of births between June and November among MS patients (P=0.004). CONCLUSION: A different pattern of MS patients' births is observed in Sicily and in Northern countries
