I only did a postgraduate degree, so I don't have the practice reading scientific studies to determine which is true. Maybe someone with more knowledge can chime in?

Idk about the op study, but I could imagine confounders with instant coffee consumption.

True, and it could also be what the person has with the coffee. I have a feeling people that drink instant coffee are more likely to add milk, creamer, or sugar.

That said, instant coffee is just freeze-dried coffee. There's a possibility its effect is no different.
