Associations between crowding index and infections (A) and deaths (B). To visualise trends in data for nursing homes, homes were combined into 20 equal-sized groups of 29–30 homes according to crowding index (black points). The red line shows the negative binomial model-based association with the crowding index, the shaded area showing the 95% CI. Each one-point increase in the crowding index was associated with a 1.92-times increase in incidence of infection (95% CI 1.74–2.11) and a 1.96-times increase in respiratory infection-associated mortality (1.68–2.28).
