Chronobiological analysis of sex differences in electrocardiographic parameters in spontaneously breathing Wistar rats under tiletamine-zolazepam anaesthesia
Fig 2
Effect of tiletamine-zolazepam on HR in Wistar rats depending on sex and LD cycle.
Differences in HR are presented as individual data points, with columns representing the mean ± SD for each group (white column – light period of the LD cycle; grey column – dark period of the LD cycle). Asterisks indicate the level of statistical significance according to Sidak’s post hoc test: *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. HR – heart rate.
