Fig. 4From: Lung function and breathing patterns in hospitalised COVID-19 survivors: a review of post-COVID-19 ClinicsBox and whisker plots comparing breathing entropy measured by SLP in COVID-19 survivors. Neither comparison between ward and ITU patients was statistically different. Entropy was calculated as (A) Standard Deviation of the Breath by Breath interval (SDBB) and (B) Root Mean Square Standard Deviation (RMSSD). Patients include those who were treated on ITU (light grey boxes, n = 34) and those who were treated on the ward alone (dark grey boxes, n = 45). Boxes represent the IQR with the median line displayed. Whiskers represent 1.5 × IQR to highlight outliersBack to article page
