Figure 1 Trend in suicide mortality by hanging/strangulation/suffocation in Serbia, 1991-2020. A: Joinpoint regression analysis; all: 1 Joinpoint; final selected model: 1 Joinpoint; B: By sex, 1991-2020; joinpoint analysis; Males: 1 Joinpoint vs Females: 0 Joinpoints. Final selected model: Males-1 Joinpoint, Females-0 Joinpoints. Rejected parallelism. ¹lndicates that the APC is significantly different from zero at the alpha = 0.05 level. APC: Average percentage change.
