eGFR, ml/min/1.73 m2    
 45 – 59 2(22.2) 0 (0.0) 2 (18.2)
 30 – 44 6(66.7) 6 (60.0) 6 (54.6)
 < 30 1(11.1) 4 (40.0) 3 (27.3)
Years of monitoring in renal clinic, median (range) 2.6 (0.7 – 8.3) 2.4 (0.3 – 7.5) 4.5 (0.9 – 12.9)
  1. Trajectories included: stable (rate of decline < 2 ml/min/1.73 m2/year, total decrease not > 4.5 ml/min/1.73 m2, and no decline by > 8 ml/min/1.73 m2 between any 2 measurements), linear decline (consistent rate of decline > 4 ml/min/1.73 m2/year throughout available follow-up and total decline ≥ 8 ml/min/1.73 m2) and non-linear (all other trajectories). We adapted trajectory definitions from prior studies and available electronic health record eGFR data from the prior three years
  2. aHealth literacy screening defined as “somewhat, a little bit, or not at all” when asked “how confident are you filling out medical forms by yourself?” [14, 15, 17]
  3. bSelf-reported confidence in CKD related self-management tasks. Scores range from 6 to 30 with higher scores indicating lower confidence [16]
  4. cAbbreviated social support measure. Scores range from 5 to 25 with higher scores indicating more support [17, 18]
