Yep, so we can be sure there is genetic confounding in the cross sectional design, and also some C confounding.

In the study we controlled for confounding effects of socioeconomic factors, urbanization (pop. density), age and gender. We don't dismiss the effect of genetics and gene-environment interactions could be an interesting next step from this first exploratory study.

It was great that you controlled for those things. Given the approach, it is hard to make a better paper. I will list some of my thoughts about potential confounding issues:

SZ has heritabiliy = ~0.8, and small shared environment effect. And would a large part of that remaining variability be explained exactly by green things. Seems a priori not so likely.

The studies of
@AmirSariaslan don't show evidence of environmental effects on mental disorders, in a neat sibling control design.1 reply 0 retweets 2 likes -

Parents with more mental disorder genes may tend to live in areas with less green things, also after controlling for SES. That could explain the results.

And, of course, green stuff could merely correlate with other neighbourhood things that are the real causal factors.

Would seem that Amir study rules out any greenness to depression effect, but then big MZ above shows it just fine. Hmm.https://academic.oup.com/schizophreniabulletin/article/41/2/494/2526097 …

He didn't look at greenness though, but urbanicity.

He looked at neighborhood which controls for greenness automatically.
