After adjusting for confounding variables, anxiety and delusions were outcomes that had a significant association with growth hormone treatment use, and the data suggested that GHT use was associated with a 2.7 times increased association with anxiety (CI: 1.0–7.4; p = 0.05) and a 14.0 times increased association with delusions (CI: 1.3–155.6; p = 0.03). This evidence concerns the gene GH1 and Delusion.
