A) female individuals (n = 24): (Δ) patients with cancer located in the fourth quadrant (Q IV); (■) average Cole's arc of the group of patients belonging to the fourth quadrant with a maximum value within the 75% ellipse (located Q IV-2); (○) Average reference Cole's arc of a healthy female population belonging to the fourth quadrant, whose maximum value is located within the 50% ellipse (Q IV-1). B) Male individuals (n = 18): (▲) patients with cancer located in the fourth quadrant (Q IV); (○) average Cole's arc of the patient group belonging to the fourth quadrant with a maximum value outside the 95% ellipse (Q IV-3); (Δ) Average reference Cole's arc of a healthy male population belonging to the fourth quadrant, whose maximum value is located within the 50% ellipse (Q IV-1).
