Fig.3. Correlation diagram of average P wave duration with creatinine
level and Spearman rank correlation coefficient and its 95% confidence
interval.
The lower and upper limits of 95% CI are greater than zero, i.e. the
correlation is positive and statistically significant (p
<0.05). The increase in creatinine concentration is
accompanied by an increase in the duration of P wave.
However, no statistically significant relationship was observed between
the dose of propafenone and the duration of the P wave. Spearman’s rank
correlation cohort rho does not differ significantly from zero (the
lower and upper limits of the 95% confidence interval differ in sign,
i.e. they contain 0; p> 0.05). This conclusion applies both
to the entire studied group of patients and to the AF and CV groups
separately.
There were no correlations between the P wave duration and propafenone
treatment (dose) among all studied patients as well in AF and CV groups.
The results are depicted in Figure 4.
