Fig. 3. Change in the annual number of total suicide, suicide attempts with PQ, and PQ fatality. PQ attempts = suicide attempts using PQ ingestion. PQ fatality (%) = suicide completion using PQ versus attempts using PQ. Note a marked decrease in the annual number of both people attempting suicide with total herbicides and with PQ, (P < 0.001). The annual PQ fatality was between around 60%-70%.
