METHODS: Baseline characteristics and laboratory results were collected and analyzed. Receiver operating characteristic (ROC) curve analysis was used to joint detection of inflammatory markers for influenza positive children, and the scatter-dot plots were used to compare the differences between severe and non-severe group.
RESULTS: Influenza B positive children had more bronchitis and pneumonia (P platelet parameters performed differently among platelet parameters and other indicators could better separate healthy children from influenza infected children than single indicator detection. The levels of platelet distribution width of children with severe influenza (A and B) infection was significantly dropped, compared with non-severe group (P Platelet distribution width could be a very useful and economic indicator in distinction and severity assessment for children with influenza.
