Low 25-hydroxyvitamin D is a risk factor for autism, ADHD, preeclampsia, low birthweight, pre-term birth and mental retardation: https://vitamindstopscovid.info/00-evi/#3.2. "Neonatal vitamin D deficiency was associated with an increased risk for schizophrenia in later life." https://www.nature.com/articles/s41598-018-35418-z.

Please see the recommendations for vitamin D3 supplemental intake quantities, according to body weight and obesity status: https://vitamindstopscovid.info/00-evi/#00-how-much.

Another likely cause of autism and ADHD is pregnant women taking paracetamol AKA acetominophen: Avella-Carcia et al." 2016 "Acetaminophen use in pregnancy and neurodevelopment: attention function and autism spectrum symptoms" https://academic.oup.com/ije/article/45/6/1987/2617189; Bauer et al. 2021 "Paracetamol use during pregnancy — a call for precautionary action" https://www.nature.com/articles/s41574-021-00553-7.

However, the hugely increased number and variety of childhood vaccines is surely the primary cause of the recent, devastating, increase in autism.

Why was autism not common historically, as women had children through their childbearing years right up to menopause. Families had 7 to 10 kids, and it was the norm, our great grandmothers were giving birth into their forties, yet no autism.

It feels so familiar to the era that big Tobacco argued correlation cannot conclude causation.

this looks like a strong correlation the interpolation matches almost perfectly, but speaking of correlation what is the P value?

I wonder if the "peanut effect" may be involved in autism also. I can think of a number of factors parents shield their children from today, that like peanut allergies tend to reduce environmental hardening. In the case of peanuts, "what doesn't kill you makes you stronger" as even if the mother during pregnancy avoids peanuts, the risk of the child eventually developing a severe reaction increases. Just a thought...

P value I mean statistical significance or probability of the null hypothesis.

Another example to visualize this data could be for example to put the data of the quantities of doses on the x-axis and the prevalence of autism per 10000 individuals on the Y-axis, the information of the years will be lost, but it could be useful to see how a direct correspondence comes.
