A Prospective Cohort Study on the Respiratory Effect on Modified Mallampati Scoring

Figure 3

A subset of obese patients from the total study population was examined. The change in score between the overall score and the inspiration (a) and subsequently the expiration (b) scores was plotted (black line) and compared to the ideal curve in which Mallampati is unaffected by respiratory status (blue line). The AUC was calculated, showing an increase in the AUC when transitioning from inspiration to expiration (c).
