Note: “X” indicates a Round “active” for Back Pain occurrence, “O” indicates a Round “inactive” for Back Pain occurrence.

aUsers” (n = 8,244) are adult MEPS respondents with back pain identified in both the Medical Conditions file and the Utilization Event files.
bNon-Users” (n = 1,949) are adult MEPS respondents with back pain identified in only the Medical Conditions file but not the Utilization Events files, i.e. individuals who did not use any services for their back pain during the MEPS 2-year panel timeframe. This table approximates Episodes-of-Pain, using MEPS Medical Conditions file to map temporal occurrence of back pain across All-5-Rounds of 2-year longitudinal panel. Tabled Data are for adults, pooled across MEPS Panels 5-through-10 (N=10,193).
