Table 6. CORRELATION OF NUMBER OF OBJECTIVE VOICE CHANGES AT 1 WEEK AND SIGNIFICANT CHANGES IN VOCAL JITTER AND MAXIMUM PHONATIONAL FREQUENCY WITH PERCEIVED EARLY AND LATE VOCAL CHANGES

100% RAP Inc, >100% increase in vocal jitter from pre-operative value; 25% MPHR-High Dec, ≥25% decrease in maximum phonational frequency (Hz) from pre-operative value. The p Values represent significant differences between symptomatic and asymptomatic changes according to number of objective voice changes (≤3 vs >3) and predictive effect of criteria early >100% RAP increase and ≥25% MPFR-High decrease (voice will vs won’t change).
