| P values are calculated in the ANCOVA model that includes baseline as covariate and visit as a fixed effect. |
| Table 1: A summary is presented of percent variation of fundamental frequency of sustained toned, reading of a standard text and electroglottography (EGG) at the first,
second and third consultation, arytenoid region oedema score was given at the top of the table. A reduction of reading intensity % was found at the second as well as third.
At the second and third examination a reduction of shimmer % of sustained tones was found. |
