This study is a joke. 20 years after exposure. Self reporting exposure. Done by a country with a huge reason to find positive results so bias is a strong possibility. No mechanism for how exposure could result in genetic modification specific to pulmonary issues.
> 20 years after exposure.
Why is this a problem? They have medical records in Iran. It is a developed country.
> Done by a country with a huge reason to find positive results
What reason? This study was done long after the Iran Iraq war.
> No mechanism for how exposure could result in genetic modification specific to pulmonary issues.
Does every study have to explain a mechanism for cause?
