Questions about this coverage

How did the left and right cover Xylitol linked to increased heart attack and stroke risk?
Of the 28 outlets on this story carrying a published leaning rating, 25% are rated left, 43% are rated centre, 32% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 66. The sections above set out what each side emphasised, in its own terms.
Is Xylitol linked to increased heart attack and stroke risk left or right?
Neither side dominates it. Of the 28 rated outlets on this story, 25% are rated left, 43% are rated centre, 32% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Xylitol linked to increased heart attack and stroke risk biased?
Xylitol linked to increased heart attack and stroke risk is one event reported by 66 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Xylitol linked to increased heart attack and stroke risk?
66 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
