Table 1 Characteristics of participants and those lost to follow-up. Characteristics of all AugUR study cohort participants were derived from information assessed at the prior study center visit (before lockdown, March 2020) from face-to-face interview, medical exams, and serum measurements (n = 2314). Shown are characteristics for (i) 1850 participants of this AugUR COVID-19 survey, (ii) 1734 participants with immediate response (i.e. questionnaire return May 12th – June 12th, 2020), (iii) 524 among the 1850 participants seen within 1 year before lockdown (i.e. March 2019 – March 2020), (iv) 350 non-responders (known to be alive, not participating in this survey, consent to be part of AugUR study platform; 112 not contactable, 238 contactable), (v) 114 who died between prior visit and this survey. Shown is median [inter-quartile range], if not noted otherwise
