However, the analyses provided by the pharmaceutical industry to regulatory authorities often do not present safety and efficacy data by sex. Novartis has started a gender-medicine project called MetaGeM, which includes nine observational studies sponsored by Novartis Farma, Italy; conducted in Italy between 2002 and 2013 in a range of different clinical areas. The MetaGeM project aims to analyze and describe by means of post hoc analyses and meta-analyses, clinical outcomes, therapeutic approaches, and safety data of these studies, by sex: PSYCHAE; GENDER ATTENTION in psoriasis; Synergy in psoriatic arthritis; ICEBERG in HBsAg carriers; SURF and CETRA in liver- and renal transplanted patients, respectively; DEEP in Parkinson's disease; and EVOLUTION and AXEPT in Alzheimer's disease. The present paper describes the methodology of the MetaGeM project.Keywords: gender-medicine, MetaGeM project, methodology
