Figure 4. Odds ratios for mortality at 30 days.

Logistic regression analysis showing odds of death at 30 days (with 95% confidence intervals) for five available metadata variables: patient sex, age (here categorised as >80 years), whether they were a care home resident, the diagnostic Ct value (here categorised as <20), and whether they were admitted to the intensive care unit. Overall there were 116 deaths within 30 days of diagnosis (out of 464 CUH patients). ICU = intensive care unit. Ct = Cycle threshold for diagnostic PCR.

Figure 4—figure supplement 1. Pairwise comparisons of mortality at 30 days, age and whether the person was a care home resident.

Each plot compares two of these three variables to visualise cross-associations, and the data are divided in each case into individuals that died (yellow) or survived (blue). The plot was produced using GGally::ggpairs().
