(A) Salivary cortisol, (B) salivary α-amylase, (C-F) pro-inflammatory cytokines, (G and H) anti-inflammatory cytokines, and (I) matrix metalloproteinase-9 trajectories in children and adolescents with osteosarcoma on clown intervention (N = 6). The graphs show the biomarkers trajectories per patient at preintervention (baseline/day 1) and at postintervention (day 3). Pediatric patients with metastatic osteosarcoma are represented in the graph by dashed lines. Full lines show pediatric patients with nonmetastatic osteosarcoma. Samples were collected +1, +4, +9, and +13 hours post-awakening (8:30 am), that is, at 9:30 am, 12:30 pm, 5:30 pm, and 9:30 pm, respectively.
