The clinical value of the RGB value of an image of the interarytenoid area for diagnosis of laryngopharyngeal reflux

I read with great interest the excellent article entitled "Image analysis of interarytenoid area to detect cases of laryngopharyngeal reflux: An objective method" by Nayak et al. [1] This is a meaningful work. The authors attempted to objectively diagnose laryngopharyngeal reflux (LPR) by analyzing the change in the RGB (red, green, blue) value of an image of the interarytenoid area. The authors found strong correlations between R and G values and both the reflux finding score (RFS) and reflux symptom index (RSI).
