"New treatment eliminates bladder cancer in 82% of patients" - current HN title (matches article)

I don't like headlines like this because they lack any necessary context. Knowing that a treatment eliminates cancer in 82% of patients isn't data unless we know more or already experts in this field. For all I know the previous treatment was 99% effective but just cost more or something. PR-style headlines very often use misleading statistics to get attention, so this wouldn't even be surprising.

- What was the previous treatment's success rate? Was it 22% or 81%?

- What are the other tradeoffs? If the previous treatment was also 82% maybe this one doesn't cause incontinence, or maybe it's non-invasive?

How you should make a title:

"New treatment eliminates cancer in 82% of patients, a major improvement"

"New treatment is first non-invasive way to eliminates cancer in 82% of patients"

"New treatment way to eliminates cancer in 82% of patients - without causing incontinence"

"New treatment eliminates cancer in 82% of patients without radiation"

Dumb question: why not rely on the article contents to provide context?

This is 81% CR in patients who had already had recurrence and progression after front-line treatment, so neither of your concerns about the headline are relevant to the actual story.
