(A) Mean ± SD of Perceived Stress Score (PSS) of control (n = 10) and Intervention (n = 9) groups for March to July. (B) Mean ± SD of overall PSS of control (n = 50, 10 subjects for 5 months) and intervention (n = 45, 9 subjects for 5 months) groups. T-test was applied to compare the scores between intervention and control groups. p < 0.05, p < 0.01 are represented as “*” and “**”, respectively when compared the scores between intervention and control groups. “#” represents p < 0.05 when compared between intervention groups (March vs. other months). “$” represents p < 0.05 when compared between control groups (March vs. other months).
