Opposite outcome observed another week later: has "stress" become "allergy"? Erroneous conclusions from ignoring a phase difference in circadian rhythm due to competing synchronization. Results from another follow-up with even more animals at a yet earlier clock hour. A difference in the opposite direction as compared to the difference observed first (Fig. 1) is noted.
