Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that cold exposure increases heart rate in humans?

Partly. Human and animal studies show cold exposure affects heart rate, but the direction is mixed: some report increases while one human study reports a baroreflex-mediated decrease in heart rate. The evidence covers only parts of the picture and does not uniformly establish that cold exposure increases heart rate in humans.
