The article describes data showing a correlation between Ozempic use and slowed progression of certain brain conditions. The study aimed to determine whether that effect came from Ozempic itself or simply from weight loss. Once researchers controlled for weight loss, the effect disappeared. In other words, correlation, not causation.

Since Ozempic was the primary reason for the weight loss, it's still causation. Although indirect.

That's an important caveat. But effectively it sounds like Ozempic typically results in a better diet, and a better diet typically results in slowed progression.
