Normalized permutation entropy (PeEn) at the sternal, mid-costal and crural area 1, 3, 9, 27 and 81 days after phrenicotomy such as in the non-denervated side.

Day 1, 3, 9, 27, 81 and non-denervated side: Median values and interquartile ranges of normalized permutation entropy (PeEn). Day 1–81 regression: Intercept and slope of quantile regression model including 95% confidence intervals. #: Significant difference between PeEn at day 1 vs. PeEn at non-denervated hemidiagphragm (corrected threshold p<0.05), §: Significant difference between PeEn at day 1 vs. PeEn at day 81 (corrected threshold p<0.05). *: Significant slope of quantile regression between time after phrenicotomy and PeEn (corrected threshold p<0.05).
