The numbers:

[...]

We estimate average total residential long-term NO2 exposure across the United States to be ∼10 ppbv for people who own a gas stove (∼18 ppbv or more for households in the top 5% of gas burned while cooking) and ∼8 ppbv from total outdoor exposure for those with electric stoves, which cause no additional NO2 exposure.

[...]

Stratifying exposure by gas stove use intensity (i.e. by amount of gas burned while cooking, [...]), we find that people in households burning the 5th, 50th, and 95th percentiles of fuel nationally on average are exposed to 0.03 (95% CI: 0.01–0.07) ppbv, 1.7 (95% CI: 0.8–3.5) ppbv, and 10.3 (95% CI: 4.8–21.7) ppbv, respectively, of additional NO2 exposure from using their gas or propane stoves.

It seems they considered water boiling in their numbers, which makes this estimation very non-portable across countries (e.g. countries where gas hobs are used, but also electric kettles are used)
