The meta-analysis is based on NO levels in the home, not stove use. Primarily this relates to gas heating. I'm aware of what it says. I'm not sure how what you're saying relates to my points. It looks to me like this article is saying "Here's good research showing that NO is linked to a 40% higher rate of asthma. Stoves produce NO so they must cause a 40% higher rate of asthma." without a study connecting the two directly. And all of this based on a meta-analysis that doesn't attempt to control for a primary trigger of asthma.
