TABLE 5.

Relationship of cannabis use status to SARS‐CoV‐2 testing

Time‐changing cannabis use status	Adjusted hazard ratio (95% confidence intervals)
Time‐changing cannabis use status	Model 1 ^a	Model 2 ^b
Current	0.83 (0.79, 0.88)^*	0.80 (0.76, 0.85)^*
Recently quit	1.11 (1.08, 1.15)^*	1.10 (1.06, 1.13)^*
Non‐user	1.00 (reference)	1.00 (reference)

Outcome was receipt of SARS‐CoV‐2 polymerase chain reaction (PCR) tests during pregnancy. Testing was treated as a recurring event outcome. All SARS‐CoV‐2 PCR tests prior to a patient's first positive test were included.

^{^a}

Model 1 is adjusted for age (21 categories: < 19, one for each year of age up to 39, 40+), race/ethnicity, neighborhood deprivation index, insurance payor and primary Kaiser Permanente Northern California (KPNC) facility.

^{^b}

Model 2 is adjusted for all covariables in model 1 plus body mass index, pre‐existing diabetes and hypertension, parity and tobacco smoking status.

Significant at P ≤ 0.05.
