Table 3 Association between COVID-19 death/population density and previous PM2.5 concentrations in 24 districts of Lima

From: Association between air pollution in Lima and the high incidence of COVID-19: findings from a post hoc analysis

COVID-19 deaths/population density Crude coefficient 95%CI Adjusted coefficient 95%CI
PM2.5 0.0016** 0.0008 0.0023 0.0014* 0.0006 0.0023
Sex ratio 0.019 −0.005 0.044 0.009 −0.010 0.029

Food markets 0.029 −0.002 0.060 0.024 −0.007 0.055
  1. The model was adjusted for PM2.5 level, sex ratio (female deaths: male deaths), and food markets (number of food markets per district and age [years] at the moments of death by COVID-19). Data for the PM2.5 level (μg/m3) correspond to the average data per district obtained daily from 2012 to 2016
