Final multivariate models for acute endophthalmitis after cataract extraction
| Risk factor | Definition | All endophthalmitis | Culture positive endophthalmitis | ||
|---|---|---|---|---|---|
| OR (95% CI)* | p Value | OR (95% CI)* | p Value | ||
| Odds ratio (95% confidence intervals) of all endophthalmitis and culture positive endophthalmitis in backwards stepwise multiple logistic regression models that included the following covariates: IOL type, PCR, sex, and type of operation. Sex and type of operation dropped out of the final models. | |||||
| IOL type | All PMMA | 1.0 | – | 1.0 | – |
