The study did not present the dogs with samples from “years before” and did not have an accuracy of 98%. It had a sensitivity (percent of positive samples called positive) of 70% for one dog and 80% for the other. Their specificity (percent of negative samples called negative) was 90% and 98%.
Since there were 60 positive samples and 40 negative samples, their accuracies were 82% and 91%, respectively.
Not 98%. And with samples from patients currently diagnosed (or controls).
“…linked to higher risk of strokes.”
No. To link it to a higher risk of strokes, you would need to find more strokes than expected in people consuming it vs those who don’t, after accounting for confounding factors.
What this study found was that human cerebral microvascular endothelial cells in culture change gene expression when exposed to the sweetener.
Prior studies suggest an epidemiological link to strokes, but the way this is reported is trash.
