What is the ratio of improvement between those who take the new drug versus those who takes the traditional one. Please explain

A double-blinded drug trial looking at the effectiveness of a new blood pressure medication was conducted on a sample of hypertensive adults. Out of 1000 people who took part, 300 received the experimental drug, 300 received a traditional drug and 400 received a placebo. In total, 700 participants showed an improvement, with 200 of those coming from the experimental drug group. Of those who did not improve, 150 of them were in the placebo group.
