N, number of measurements (one measurement on two adjacent patches in each bird); BPU, blood perfusion unit; baseline, stabilized pretreatment values for the two adjacent patches on each bird; *P-value in the unpaired t-test, assuming equal variances; †P-value in the unpaired t-test with Welch's correction, assuming unequal variances.
