ZeroHedge - On a long enough timeline, the survival rate for everyone drops to zero

The percentage of healthcare workers testing positive for COVID in each group was tracked to determine how effective or ineffective higher-quality masking was in preventing infection.

Unsurprisingly, the results confirmed that there is essentially zero difference between surgical or N95 respirators when it comes to tests results.

In the intention-to-treat analysis, RT-PCR–confirmed COVID-19 occurred in 52 of 497 (10.46%) participants in the medical mask group versus 47 of 507 (9.27%) in the N95 respirator group (hazard ratio

, 1.14 [95% CI, 0.77 to 1.69]). An unplanned subgroup analysis by country found that in the medical mask group versus the N95 respirator group RT-PCR–confirmed COVID-19 occurred in 8 of 131 (6.11%) versus 3 of 135 (2.22%) in Canada (HR, 2.83 [CI, 0.75 to 10.72]), 6 of 17 (35.29%) versus 4 of 17 (23.53%) in Israel (HR, 1.54 [CI, 0.43 to 5.49]), 3 of 92 (3.26%) versus 2 of 94 (2.13%) in Pakistan (HR, 1.50 [CI, 0.25 to 8.98]), and 35 of 257 (13.62%) versus 38 of 261 (14.56%) in Egypt (HR, 0.95 [CI, 0.60 to 1.50]). There were 47 (10.8%) adverse events related to the intervention reported in the medical mask group and 59 (13.6%) in the N95 respirator group.

52 of 497 participants who wore medical masks got COVID-19, and 47 of 507 in the N95 group got COVID-19.

No matter how “high quality” your mask is, it’s entirely irrelevant.

The researchers also took pains to ensure that the control and treatment groups shared as many similarities as possible.

They excluded workers who could not pass a fit test, had laboratory-confirmed COVID, or “had received 1 or more doses of a COVID-19 vaccine with greater than 50% efficacy for the circulating strain.”

Yet none of that mattered; there was no difference in outcomes between the medical and N95 level masks.

Great at keeping dust out ya mouth. Viruses, probably not so much.
