Maternal Mortality Ratio (MMR) per 100,000 live births, and the incidence of COVID-19 per 100,000 inhabitants, per month 2020*, and predicted** MMR values with 95% confidence interval, for the same period. Bahia, Brazil, 2020. Source: Brazilian’s Mortality Information System (SIM/DATASUS) and Live Birth Information System (SINASC/DATASUS); COVID-19 Bahia Epidemiological Bulletins No. 01, 04, 35, 67, 98, 129, 160, 190, 221, 251 and 282/2020. *Data updated on February 04, 2021. **Values for 2020 predicted by Holt-Winters additive exponential smoothing, based on the 2011–2019 monthly MMR time series. Smoothing coefficients: Alpha = 0.10; Beta = 0.00; Gamma = 0.00. Forecast Accuracy: Scaled Mean Absolute Error (MASE) = 0.57; Symmetric Mean Percentage Absolute Error (sMAPE) = 0.28; Mean Absolute Error (MAE) = 14.16; Root of the Mean Quadratic Simulation Error (RMSE) = 16.53
