rome_iv_child_functional_dyspepsia: Rome IV Diagnostic Criteria for Child Functional Dyspepsia

Description

Evaluates the **Rome IV criteria** for diagnosing **Functional Dyspepsia** in children and adolescents. Functional dyspepsia is sub-classified into Postprandial Distress Syndrome (PDS) and Epigastric Pain Syndrome (EPS). Diagnosis requires symptoms to be present for at least 3 months, with onset at least 6 months prior, and the absence of organic disease that explains the symptoms.

                                    organic_disease_excluded, symptom_onset_ge_6_months,
                                    symptoms_active_last_3_months)
