Box-whisker plots for outcomes with statistically significant differences (Friedman rank sum test with Bonferroni correction for multiple testing). The difference in the score for each experimental conditions (NP: 22 °C, PPE; WN: 27 °C, no PPE; WP: 27 °C, PPE) were calculated in relation to the reference condition (NN, 22 °C, no PPE (0))
