^aDifferences in death among quarters, areas, and causative hazard were compared by Chi-Square test. ^b Differences in death were significant in the comparison of the second and the third quarter, and the comparison the third and the fourth quarter (p = 0.018). ^c Differences in death were significant in all areas pairwise comparison (p = 0.017) except comparison of village and town (p = .0558). ^d Differences in death were significant in all causative hazard pairwise comparison (p = 0.018) except comparison of chemical agents and toxic insects/food products (p = 0.053), and chemical agents and poisonous plants (p = 0.191)
