History of pauses, mouth breathing, nasal obstruction or enuresis in children > 4years; palpable P2 on examination or adeno-nasopharyngeal ratio (ANR) > 0.83 had an area under the curve > 0.6 (0.61-0.65). Combinations with the highest diagnostic accuracy included mouth breathing, palpable P2, hypoxia and ANR > 0.83 (AUC 1.0); mouth breathing, palpable P2 and hypoxia (AUC 0.86) and mouth breathing and a palpable P2 (AUC 0.81); the latter being most feasible.Conclusion The diagnostic accuracy of clinical-radiological parameters for pulmonary hypertension in children with adenoid hypertrophy is modest. Combined parameters yielded increased accuracy but reduced feasibility. ER -
