What kind of drugs are these?

Logic

Two new drugsAntiCynicismiaandAntiMisantropiaare currently in a clinical trial phase, where the pharmacists determine whether the drugs are safe to use. The trial was divided into five distinct groups and the results of the experiment are as follows:

Drug name	AntiCynicismia	AntiMisantropia
Group A	436 out of 545 people were cured, or80%success rate	9 out of 10 people were cured, or90%success rate
Group B	245 out of 350 people were cured, or70%success rate	16 out of 20 people were cured, or80%success rate
Group C	48 out of 80 people were cured, or60%success rate	21 out of 30 people were cured, or70%success rate
Group D	10 out of 20 people were cured, or50%success rate	180 out of 300 people were cured, or60%success rate
Group E	2 out of 5 people were cured, or40%success rate	320 out of 640 people were cured, or50%success rate

It may seem like AntiMisantropia is a more effective drug based on the success rates on different groups. However, this is not true!

Given that $x\%$ is the difference in success rates between these two drugs, find the value of $x$ .
