In 2016, COPD was the third deadliest killer in Pakistan. Could the decrease in smog have saved enough lives to offset the death tool due to COVID-19?

According to [this article from 2016 in The News](https://www.thenews.com.pk/print/165947-COPD-spreading-fast-in-Pakistan-experts), there were 7.1 million COPD patients in Pakistan with an estimated 6 million more possibly undiagnosed. The leading cause of COPD is smog, smoking, and mosquito coils. Approximately 210,000 people die to [COPD in Pakistan per year](https://dailytimes.com.pk/330771/more-than-6-9-million-people-suffer-from-copd-in-pakistan/).

The [prevalence of this condition in Pakistan](https://tribune.com.pk/story/1263519/pulmonary-disease-copd-kills-one-person-every-10-seconds/) is 18.5% and COPD patients with comorbidities such as diabetes or HBP are 26.7%. Out of these, 76.7% of COPD patients experience exacerbations.

I am not a statistics guru, but I am wondering if we can calculate how many lives would have been saved due to the reduction in pollution levels caused by the lockdown. Let me know if you are aware of data that can be used to calculate this.
