Fig. 3. The results of attempt for apple test (AAT) and human intruder test (HIT) in CUMS and CON groups.

A The schematic of the AAT. B The duration of attempts for apple for total three days. C The frequency of attempts for apple for total three days. D The schematic of the HIT. E The duration of the anxiety-like behaviors in each phase. F The total duration of the anxiety-like behaviors in four phases. *P < 0.05. Subject S2 in CUMS group dropped out of AAT and HIT due to diarrhea, so we imputed the median value for each behavior in CUMS group as the value of S2 in statistical analysis.
