Abstract
INTRODUCTION: A common subtype of vulvodynia is provoked vestibulodynia (PVD), characterized by severe pain upon contact to the vaginal entrance. Some researchers have further delineated the PVD group based on pain onset (primary vs secondary PVD, referred to as PVD1 and PVD2, respectively). AIM: This study aims to review available evidence regarding sociodemographic variables, pain characteristics, medical history and examination findings, quantitative sensory testing, genetic markers, psychosocial/sexual/relationship function, treatment outcome, and brain imaging in women with PVD1 and PVD2. METHODS: All available data related to PVD1 and PVD2 were reviewed. MAIN OUTCOME MEASURES: There is mixed evidence supporting the assumption that women with PVD1 fare worse on all variables investigated. RESULTS: The review indicated that although women with PVD1 seem to fare worse on many variables examined (eg, pain severity, genetic markers), many studies also indicated no significant group differences or-less commonly-that women with PVD2 fare worse on some variables (eg, sexual function). CONCLUSION: Although it has been suggested that different pathophysiologic processes are involved in the development and maintenance of PVD1 and PVD2, the data reviewed were mixed. While most studies indicated that women with PVD1 have higher pain intensity, higher sensitivity, more genetic influence, more evidence of inflammation, lower successful treatment outcomes, and different neural activation patterns and structural findings, these results were not consistently reported. In addition, the data for subgroup differences in psychosocial, sexual, and relationship variables were not convincing. A more precise definition of primary and secondary PVD is needed, and importantly, prospective, longitudinal studies are essential for clarifying any differences within these PVD subgroups.

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
