At very mild dehydration levels, defined as only 1.5 percent of water loss in the body, the test group experienced headaches, fatigue, difficulty in concentrating, and poor memory skills.
Without the comma like ...levels defined as only 1.5 percent of water loss in the body..., is the phrase unnatural or incorrect to native English speakers?
What difference is there if the phrase without a comma is possible in the sentence?
Thank you so much as usual in advance!
