As astronomer Carl Sagan famously said, “absence of evidence is not evidence of absence.” Plaintiffs have not gotten the message. They often allege that a defendant’s marketing or labeling statements are false and misleading on the sole basis that there is purportedly no evidence (or insufficient evidence) proving their truth.

Rather, she alleges only an absence of supporting evidence for the statement—and generally, in a conclusory manner.
