2.7 Statistical analysis
Categorical variables are expressed as numbers and percentages.
Continuous values are reported as mean ± 1 standard deviation. Linear
regression analysis and Bland-Altman plots with assessment of systematic
bias and 95% confidence intervals were used to compare LS and CP pacing
characteristics. Systematic differences in measurements between the 2
modalities were assessed using Student test. All tests were two-sided
and a p value <0.05 was considered as statistically
significant. Statistical analyses were performed using Prism Graphpad
and SPSS Statistics 24 (IBM Corporation, Armonk, NY, USA).
