ADM users were defined as patients who took the drug for at least the first 6 months of follow-up evaluation.
How do you know if they took the drugs?

The strong signal visible in interstitial cells between testis tubules (Figure 1D) was also present in sections of testis from Ythdc2 null mutants stained with YTHDC2 antibody, indicating that the staining in interstitial cells is non-specific.
The argument here suggests that this Anti-YTHDC2 antibody is specific to its target (ie, YTHDC2), or not so specific?

Clinical studies are most often conducted to support a PMA. Only a small percentage of 510(k)s require clinical data to support the application.
-
An approved IDE permits a device to be shipped lawfully for the purpose of conducting investigations of the device without complying with other requirements of the Food, Drug, and Cosmetic Act (FD&C Act) that would apply to devices in commercial distribution.
Not sure if charging patients to participate and use an investigational device would be considered "commercial distribution".

For Class III devices, a premarket approval application (PMA) will be required unless your device is a preamendments device (on the market prior to the passage of the medical device amendments in 1976, or substantially equivalent to such a device) and PMA's have not been called for. In that case, a 510k will be the route to market.
-
If your device is classified as Class I or II, and if it is not exempt, a 510k will be required for marketing.

This is the page to learn FDA device regulation.
-
An investigational device exemption (IDE) allows the investigational device to be used in a clinical study in order to collect safety and effectiveness data required to support a Premarket Approval (PMA) application or a Premarket Notification 510(k) submission to FDA.
No matter what Class the device is, this must be applied first for the device to even be studied in a clinical trial.
-
Product requiring PMAs are Class III devices are high risk devices that pose a significant risk of illness or injury, or devices found not substantially equivalent to Class I and II predicate through the 510(k) process.
It is important to determine if the device is Class III or not.
-
All registration information must be verified annually between October 1st and December 31st of each year.
-
medical devices must register their establishments with the FDA.
-
most Class III devices require Premarket Approval
-
Manufacturers must list their devices
-
Clinical studies with devices of significant risk must be approved by FDA and by an Institutional Review Board (IRB) before the study can begin. Studies with devices of nonsignificant risk must be approved by the IRB only before the study can begin.
Either high risk or low risk, IRB is necessary. High risk one needs FDA approval, too, for clinical study of the device.

New device with no substantial equivalent but with a low risk can file an application to be classified as De Novo and request FDA to make a risk based classification.

Test if this shows up in another list.

Finally found its BMI distribution... turns out to be in demographic category. So most samples from this study have BMI > 24. Good for us.

Obesity was highly prevalent among the study sample; 64.6% of females and 41.2% of males were obese according to Polynesian cutoffs (BMI ≥ 32 kg/m2). Females were less likely than males to have hypertension (31.7% vs. 36.7%) but equally likely to have diabetes (17.8% vs. 16.4%).
Those with obesity but not hypertension or diabetes can be our candidates.
The data set can be found here: dbGaP Study Accession: phs000972.v2.p1 https://www.ncbi.nlm.nih.gov/projects/gap/cgi-bin/study.cgi?study_id=phs000972.v2.p1

‘Metabolically Healthy Obese’
I found some TOPMed and GTEx studies have candidate samples that match this criterion: more specifically, obese but without T2D or CVD history, from dbGAP. I have annotated those studies with tag "data commons examples" as this one.

Samoans have been studied for >40 years with a focus on the increase in, and levels of, BMI, obesity, and associated cardiometabolic conditions due to economic modernization
This one may contain the sample we need. need to check their publications.
