The table isn’t in the paper, only their supplemental materials. Notice there are two significant interaction effects: one for the dollar damage of a hurricane (highlighted in green), and the other for the minimum pressure (highlighted in yellow). Both are severity measures. You might think that because both coefficients have the same sign, they both are consistent with the story that, as hurricanes become more severe, the death rate goes up faster for “female hurricanes” than “male hurricanes.”
