这题的题干读不太懂,请帮忙!

Treatment for hypertension forestalls certain medical expenses by preventing strokes and heart diseases. Yet money so saved amounts to only one fourth of the expenditures required to treat the hypertensive population. Therefore, there is no economic justification for preventive treatment for hypertension.

请问红色标志的句子是什么意思？谢谢！

因此而省下的钱只有花在治疗hypertensive的人的身上的１／４．

大意是说，某种病的疗法可以通过防止中风和心脏病来减少一点的费用，但是减少的费用只有需要治疗该病的人们医疗花费的１／４，所以对这种疾病的预防性的治疗没有什么经济意义．
