Surfers three times more likely to have antibiotic-resistant bacteria in guts

I wonder what the p value is. 9% vs 3% in a sample of 300 doesn’t sound that compelling.

Yeah, it would be interesting to do the same study in California and see if the percentage was higher or lower, they could even break it down by closest major city, San Diego, Los Angeles, San Francisco, etc.

I couldn’t find 9 vs 3 in any of their published papers. Their most recent has 6 v 1.5 (p of .04) from a review of existing epi data, and not an original collection (https://www.sciencedirect.com/science/article/pii/S016041201...)

Exactly my thinking. It's 0.0256 using a chi-squared test, which is definitely below the standard threshold.
