### Study description

Expansion Area 3 (EA3) studies aim to acquire additional clinical data centered around specific diseases through biobanks.

**Aim:** The endometriosis deep phenotyping study aimed to explore the genetic background on endometriosis related chronic pain by identification of those endometriosis cases who suffer from chronic pain (lasting from three months and over) and those with abnormal pain response.

**Methods:** Data was captured from five biobanks, Auria, Helsinki, Central Finland, Borealis, and Eastern Finland biobanks. Endometriosis data contains information about hospital administrated drugs, such as epidural and spinal infusions, and information about the experience of pain based on text mining from patient records.

**Data:** The Endometriosis data has been placed in the Sandbox and is available for analysis. The Endometriosis samples are from DF12 and data has been collected from 5/6 hospital biobanks. Data collection time is until 23.3.2023.
