The highest number of publications came from USA, followed by Germany. The publication activity increased significantly for Poland, Turkey and South Korea and went down for Finland, Sweden and Japan in the second block. Data indicates that total output is concentrated in 8 sub-disciplines. Highest output (38.9%) is in the sub-discipline of immunology followed by food allergy (23.9%).
