It’s an early, honest signal — not the final word, and we say so. 30 complete before-and-after tests is enough to show a real change: the symptom results clear statistical significance at p < 0.001, with a large effect — meaning the odds of seeing this by chance are less than 1 in 1,000. It’s still small enough that the averages will move as more come in.
That’s why every figure here carries its count, and why we update them. We’d rather show you a real number with its limits than a polished one you can’t check.
