*
Number of participants with non-missing scores for at least one of the outcomes: the actual denominator varied slightly for the three outcomes measured due to missing values; not all exposure measures were completed by participants (duration of displacement and warning received), therefore the number of participants in these categories do not sum to the total flooded and displaced exposure group.
