Abstract
BackgroundPostural orthostatic tachycardia syndrome (POTS) is a chronic form of orthostatic intolerance that primarily impacts female patients of childbearing age. The role of sex differences in POTS is not well understood. We sought to identify sex differences in diagnosis, symptoms, comorbidities, and treatments in female and male patients diagnosed with POTS.MethodsA comprehensive survey was designed in partnership by Dysautonomia International (East Moriches, NY) and Vanderbilt University Medical Center (Nashville, TN). Patients were recruited through Dysautonomia International’s website and social media channels. The survey was delivered online through a secure research data capture database. Responses were analyzed according to biological sex. Continuous variables are presented as median (25th percentile-75th percentile), and categorical variables are presented as number and proportion of participants.ResultsA total of 8919 patients reported a physician diagnosis of POTS and were included in this analysis. The majority of respondents were female (93.7%). Female and male patients experienced misdiagnosis at similar rates (76.2% vs 74.9%, P = 0.5) and saw a similar number of doctors before diagnosis (5 [3-8] vs 5 [3-8], P = 0.9). Despite these similarities, diagnostic delay was longer for female, compared with male, patients (1.50 [0.25-5.25] years vs 0.92 [0.08-2.91] years, P < 0.001).ConclusionsDespite the primarily female demographic of POTS patients, female patients experience more challenges with diagnosis than male patients. Increased awareness and recognition of POTS may help to reduce the diagnostic challenges in both female and male patients, and improve treatment and management for individuals living with this debilitating disorder.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
