^a P-values are calculated by Kruskal-Wallis Test or ^b Fisher's-Exact Test

^c Intake of one tomato extract capsule per day equals 105 mg lycopene per week.

^d Moderate physical activity, e.g. brisk walk, cycling at regular pace, doubles tennis, swimming

^e 5-point scale with 1 = excellent, 2 = very good, 3 = good, 4 = fair, 5 = poor

^f 5-point scale with 1 = very energetic, 2 = moderately energetic, 3 = somewhat energetic, 4 = fatigued, 5 = very fatigued

^g 5-point scale with 1 = very happy, 2 = happy, 3 = up and down, 4 = unhappy, 5 = very unhappy

* p < 0.05 indicates a significant difference between groups
