EVENT
Wearable sensor data showed a statistically significant but weak correlation with patient-reported severity and duration of key ILI symptoms, as well as QoL outcomes. The total ILI burden on daily step count and sleep duration over the course of an ILI event correlated with patient-reported severity of fever, cough, headache, muscle ache, chills, fatigue, and QoL outcomes (hours of missed work; Correlations between patient-reported outcomes (y-axis) and wearable sensor data (x-axis). The color shading and the value printed in each cell indicate Spearman ρ correlation coefficient for the association between the variables in the corresponding row and column.
