Effects of the execution amount of subdivisions of EFECBSC on EBSMR trends of total (A), man (B) and woman (C, D) charcoal-burning suicide analysed by stepwise multiple regression analysis. Ordinates indicate EBSMR trends between 2009 and 2018 and abscissas indicate execution amount of EFECBSC sub-divisions (¥ per population). Light blue, grey, blue and red spheres indicate national, total (men plus women), male and female EBSMR trends and population sizes, respectively. Black and red lines indicate the regression lines of significantly positive (reduced suicide mortality) and negative (increased suicide mortality) factors, respectively. Total EBSMR trends of charcoal-burning suicide = −0.0012 × (municipal ELM) −0.159 (¥81.3 million of municipal ELM per 100 000 population decreased total charcoal-burning suicide by 1/100 000 per year). Male EBSMR trends of charcoal-burning suicide = −0.0068 × (municipal DLL) −0.291 (¥14.8 million of municipal DLL per 100 000 population decreased male charcoal burning suicide by 1/100 000 per year). Female EBSMR trends of charcoal-burning suicide = −0.0002 × (municipal ELM) +0.0002 x (prefectural TCS) −0.057 (¥500 million of municipal ELM per 100 000 population decreased female charcoal-burning suicide by 1/100 000 per year, but ¥526 million of prefectural TCS per 100 000 population increased female charcoal-burning suicide by 1/100 000 per year).
