Note: In 2010/11, the variable ‘size’ is missing for Rotherham NHS Foundation Trust (RFR) and Sheffield Teaching Hospitals NHS Foundation Trust (RHQ). In 2012/13, Isle of Wight NHS Trust (R1F) and Barts Health NHS Trust (R1H) did not report non-medical workforce information; therefore, we were not able to calculate the percentage of medical workforce over total workforce and the ‘Number of Students per 100 FTE’ variables.
