Candidate predictors that influence detected deaths. Dots in each plot represent observed values, whereas solid lines show moving averages using a 5-day sliding window, centered at day 3. A Proportion of cases without contact tracing delay was defined as the proportion of cases that were tested (the first test) earlier or on the same day as symptom onset. B Testing delay is the time delay between symptom onset and the final test. It was estimated by subtracting these two time points. C Death delay was defined as the difference between the time of death and symptom onset. D Ratio of tests to cases was calculated as the daily number of tests divided by the daily number of reported cases. E Reporting delay refers to the time delay between symptom onset and reporting. F Percentage of deaths that are detected using adjusted reported data and model prediction. Red circles represent the adjusted reported data. The blue dashed line represents the prediction results using the best-fitting model. The gray shaded area represents 95% confidence interval
