What does "Nonsignificant" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
"Nonsignificant" in medicine refers to a result or finding that may not be due to anything other than chance. For example, if a study is trying to find out if a new drug is better than an old one, a nonsignificant result means that any difference between the two could just be random. In other words, the new drug might not actually be better. It's like flipping a coin and getting heads three times in a row - it doesn't necessarily mean the coin is rigged, it could just be luck.
