Application of heart rate variability during blood pressure measurement in patients with somatic symptom disorder, 2020, Huang et al

Just from the abstract.
Somatic symptom disorder - so a group of people with heterogeneous somatic symptoms.
No healthy controls; no controls with a chronic non-MUS disease.
Looks like the researchers made multiple comparisons and only found a few probably random things correlated. (No indication of the strength of those correlations.)
And they assumed that a tool supposedly measuring depression is actually measuring depression, rather than aspects of a physical illness.
And then they leapt to a conclusion that surely can't be justified on the basis of this one study.

This seems deceitful to me, unless I've misunderstood something.
Scenario : Patient visits doctor about, say, non-resolving belly pain. Doctor takes patient's blood pressure a few times and decides that the patient is faking it. Patient is dismissed on the basis of a BP measurement with their belly pain unresolved. I can see this will save money, but won't actually cure anybody of anything. What is the point of doctors going to work in the morning if they always do bugger all?

If they performed ROC analysis, why wasn't the sensitivity/specificity reported in the abstract? Seems a bit suspicious.

The level of confusion here is frankly excessive. The uncertainty value of those results is essentially infinity.
Just throw dice at this point, no functional difference.
Honestly funding for medical research is completely broken. This has no possible value and is just a jumble of weird beliefs with no coherent sense or reason.

As I thought, combined sex AUC = 0.671 to detect "severe SSD", AUC = 0.71 for "depression".
Reproducibility tends to be even lower, meaning this measure (HRV) is quite poor at making these predictions given the evidence in this study.

Hold on a minute I thought focussing on symptoms, catastrophising, health anxiety is supposed to be what keeps us feeling ill. But if the researchers decide it’s a good idea to measure heart rate that’s ok after all.
