| Table 2: Spearman correlations for percent change of the acoustical parameters compared with oedema of the arytenoids at the second and third consultation. The results
of jitter were not found in reading. A comparison was made of the Spearman correlation quotient between arytenoids swelling changes and MDVP and EEG at the second
and third consultation. The jitter measures were due to a few aberrant variables. |
