My thoughts as several things can be true at once:

- This study is the source of LinkedIn ads from climate change where they try to convince people to move from gas to electric because of bad health effects

- But it doesn't invalidate the study, because of course burning something indoors creates some sort of emission, which may causes asthma in kids

- But its not relevant for me because I'm a single adult not a child and I don't cook that much anyway

- And even when I used to have a gas stove, I used my induction burner more often as its more powerful and makes less waste heat compared to my gas stove

- and the reason I bought an induction wok burner from aliexpress, it can go much hotter than my gas stove

- But one thing that gas stoves excel is even the cheapest gas stoves have a smooth analog control, making it possible to gently heat things, which is important for cooking omelette. For the induction burners I have, it uses on off control, which will scorch the food if your setup (food + cookware) have low thermal mass to smooth it out. You think with the advancement of power electronics because of EV, ebikes, drones and AI data center power supplies someone is able to make a cheap induction burner with analog power control
