From: Impact of meteorological variation on hospital visits of patients with tree pollen allergy
Annual trends of minimum temperature, tree pollen counts, and patients with tree pollen allergy. Value for each variable is following; monthly mean value of minimum temperature in March for minimum temperature (solid line), monthly mean value of tree pollen counts in March and April for tree pollen counts (dashed line), and total numbers of tree pollen-sensitized patients visited in hospital from April through July for patients with tree pollen allergy (bar graph).
