Abstract
Terho EO [Department of Pulmonary Diseases, University Central Hospital, Kuopio, Finland], Lammi S, Heinonen OP. Seasonal variation in the incidence of farmer's lung. International Journal of Epidemiology 1980, 9: 219–220. The seasonal variation in the incidence of 78 consecutive cases of farmer's lung was investigated according to a statistical method described by Roger. The cyclic trend was statistically highly significant (P < 0.0001) and the centre of gravity of incidence appeared in the latter half of April. The reasons for the variation are discussed.Keywords
