Do a simple experiment with a prayer condition and no prayer condition, ultimately saying what the probability that things happened by chance alone, not related to the prayer. If that probability is low then the logical conclusion is that the isolated variable was prayer.
We can also further isolate the groups into sickness, objects and events. Because I have heard (I’ll have to dig them up) of studies that did find prayer healed the sick quicker than not prayed-for groups. However some have disputed that as electromagnetic fields and positive energy (dotdotdot).

Actually, you have the it the other way around. People who are sick and know they are being prayed for do worse.
It’s called a Placebo Effect. The person believes so much that the prayer will help them, that their body doesn’t work as hard to recover.
Sloth – No, it’s the correct way. They believe that they don’t need any other effect to help heal them, as in a full reliance on the prayer, so there body stops trying to recover normally. The effect with medicine is that they believe they have something helpful inside them that in tangibly there.
