Fig. 1From: Different chest HRCT scan protocols change the extent of ground glass opacitiesa Total Warrick score for all participants by scan method. Two participants had identical Warrick scores on all scans (score 7 on supine, 5 on prone, 5 on post-positive expiratory pressure (PEP)). Scores for the prone scans and post-PEP scans were significantly lower compared to the supine scans, but no statistically significant difference was seen between prone scans and post-PEP scans. b Data presented as a box-and-whisker graphBack to article page
