Differences in exogenous factors (diet plan, drugs and comorbidities) involving study samples might account for several of the variations, and are hard to handle for across studies. We have checked for probable effects of key drugs utilised within this patient population. We utilized Fisher’s Exact Test to look for statistically significant associations in between cognitive outcomes (AD vs MCI vs CN) and use of many medication classes. As expected, there was a statistically considerable difference inside the use of cholinesterase inhibitors (unadjusted Po0.0001) also as memantine (unadjusted P 0.003), the two forms of drugs typically utilised to treat Alzheimertype dementias, amongst the diagnostic groups. Use of antidepressants, antipsychotics, anxiolytics, corticosteroids and statins did not differ drastically amongst the diagnostic groups. Therefore, only the cholinesterase inhibitors and memantine were additional examined for correlation with the metabolites. We did note marginal effects of these agents on a couple of metabolites such as MET, MET/GSH ratio, and a number of unknown metabolites. None of those effects completely accounted for the reported metabolic variations between diagnostic groups.
