Each sheet contains an increasingly cleaned format of the overall SSRI dataset, this is to display continuity and progression of data cleaning. Datasets after the 'No SEX and AGE missing or unknown' worksheet are the final cleaned formats of the original 'uncleaned SSRI dataset'. Final cleaned sheets are named as follows: 'No DPX', 'Male only', 'Female only', 'Paediatric', 'Adolescent', 'Adult', and 'Elderly'.
