CRC = colorectal cancer; OR = odds ratio; PCP = primary care physician.

^*With adjustment for an unmeasured confounder having an OR of CRC death of 0.9 or 0.75 (n = 54 160). Bold indicates that CIs include 1.0 (PCP effect becomes null) or are >1.0 (PCP effect is reversed).

^†OR of CRC death comparing persons with an unmeasured confounder vs. those without the confounder.

^‡Prevalence of unmeasured confounder in those with 5 to 10 PCP visits.

^§Prevalence of unmeasured confounder in those with 0 to 1 PCP visit.
