OR stands for odds ratio, CI for confidence interval
¹Variables in multivariate models were selected by stepwise regression, using a cutoff p value of 0.1. The number of patients in the model may be lower than the total number of patients due to missing co-variables in some individuals
²The models are not changed and the association with antibiotics is still significant when the variable “intraabdominal bacterial infection” is forced into the model
³SAPS2 was not included in the model since it is composed of variables which are presented separately in the model
⁴Within 2 weeks before candidemia (cases) or matched time period (controls)
⁵Within 4 weeks before candidemia (cases) or matched time period (controls)
⁶The association between these classes of antibiotics and candidemia is still significant when the variable “number of antibiotics” is added in the model (independent variables)
