Yeah well that is my point results or GTFO. Secondly they can and are able to easy manipulate results. I smell fish, that's all. Just don't trap into it. Btw just to close it out with some cool studies, to also show the side from a different standpoint!

RESULTS: Results were obtained from logistic regression models, adjusting simultaneously for all the measured hormones and age. Men with higher levels of testosterone were more likely to have vertex baldness (odds ratio [OR] = 2.5, 95% confidence interval [CI: 0.9 to 7.8] per 194 ng/dL increment of testosterone). In addition, for each 59 ng/mL increase in IGF-1, the odds of having vertex baldness doubled (95% CI [1.0 to 4.6]). Those who were found to have higher circulating levels of SHBG were less likely to have dense hair on their chest (OR = 0.4, 95% CI [0.1 to 0.9] per 24 nmol/L increment in SHBG]).
In summary, regulation of human hair growth by androgen is probably mediated by IGF-1 in the dermal papilla. In male scalp, high levels of IGF-1 may increase the androgen receptor activity and dihydrotestosterone levels and these result in an increased propensity for baldness.
CONCLUSION: Older men with vertex balding have lower circulating levels of IGFBP-3 and higher levels of IGF-1 when controlling for IGFBP-3 level
