Deadly floods and their causal factors: A case-control study in Iran between 2005 and 2018

Flood hazard characteristics play a key role in flood-induced mortality. Therefore, it is crucial to evaluate the associations between these factors and flood fatalities. This case-control study was performed in the flood-prone regions of Iran with recorded flood-induced mortality rates during 2005–2018. In total, 369 subjects completed the survey (123 cases and 246 controls); they were selected from 12 provinces and 30 cities.
