The entire group (men plus women) treated with isosorbide dinitrate/hydralazine (I/H) had a significantly improved the composite score (p = 0.016) compared with the entire group (men plus women) in the placebo arm. Women as a group had better composite scores than men (p = 0.049); however, there was no gender-by-treatment interaction (p = 0.806).

The p values compare isosorbide dinitrate/hydralazine (I/H) with placebo in each group. Mortality was reduced by I/H in both men and women, with a slightly greater effect in women. First heart failure hospitalization was similarly reduced in both men and women, whereas change in quality of life (QoL) was improved in both genders without gender-by-treatment interaction.
