Overall, we found that there was high agreement between raters, Dr. Mesallam said. The correlation between RFS and RSI symptoms and signs reveals that hoarseness or throat clearing and globus sensation were the main RSI symptoms that correlate significantly with RFS signs.

Dr. Mesallam reported that the RFS scores ranged from 0 to 30 while those of the RSI varied from 13 to 38. There was a high agreement between the raters’ scores, demonstrating high inter- and intra-rater reliability of the RFS. The RSI and RFS were highly correlated. Hoarseness was highly correlated with vocal fold edema and thick laryngeal mucus, while excessive throat clearing correlated significantly with thick endolaryngeal mucus.
I believe the study demonstrates a highly significant correlation between the RFS and RSI, Dr. Mesallam said. This strongly confirms the validity of both tests as good diagnostic instruments for LPR.
