Bend it like Beckham or fix them like Florence-proportional representation of healthcare in New Year honours: an observational study.

Objectives: To compare the proportional representation of healthcare workers in receipt of New Year honours (NYHs) with workers in other industries and to determine whether the NYH system has gender or geographical biases.

Design: Observational study of the UK honours system with a comparative analysis of proportional representation of the UK workforce and subgroup analyses of gender and geographical representations.

Participants: Recipients of NYHs from 2009 to 2018.

Complex dynamics in a three-level trophic system with intraspecies interaction.
