  1. Direction of effect for SAPALDIA, ECRHS and NFBC: a positive sign indicates that an increase in methylation is associated with higher level of lung function (cross-sectional models) and with an attenuation of lung function decline in the prediction models (change in lung function). In ALSPAC children, a positive sign indicates that an increase in methylation is associated with higher level of lung function (cross-sectional models) and with lung function growth in the prediction models (change in lung function)
