In addition to the UHC for service coverage index and GHS index, there are other variables that determine observed COVID-19 case fatality and infection rates. In order to assess effects of these variables on COVID-19 case fatality and infection rates, the study included in the analysis as control variables set. Based on the previous research results, we selected the following indicators as a covariate to assess social risk factors for susceptibility and acquire infection and case fatality rate. These included the median age of the national population, population density per square kilometer; the prevalence of obesity among adults aged 18 + years expressed as a body mass index (BMI) ≥ 30 kg/m2, percentage who currently use tobacco, the ambient and household air pollution attributable death rate (per 100,000 population), and disease specific mortality of chronic obstructive pulmonary disease (COPD).

The details description of the explanatory variables such as of the UHC for service coverage and GHS component as well as other covariates is attached in the supplementary annex ( Additional file 2 ).
