(A) Median time from postural orthostatic tachycardia syndrome (POTS) symptom onset to first physician presentation for POTS (left), and time from first physician presentation for POTS to POTS diagnosis (right) in female vs male patients. Time from onset to presentation and from presentation to diagnosis were both significantly longer in female patients. The inset is a zoomed-in version of the main figure, to better illustrate the median and interquartile range. (B) Challenges with diagnosis in female and male patients. A similar proportion of female and male patients were misdiagnosed and were told their illness was psychological. More female than male patients were told their illness was “all in their head.”
