From: Contributions of the thumb and index finger to tip pinch force sense

Variable Error (VE) values across multiple trials as a function of sex (males and females), fingers (thumb, index finger, and pinch), and force levels (5%, 10%, and 20% MVIC). The y-axis represents the VE values (in Newtons, N), and the x-axis represents the force levels. Statistical significance is denoted by * for P < 0.05 and ** for P < 0.01.
