Fig. 2From: Mathematical pattern of Kessler psychological distress distribution in the general population of the U.S. and JapanDistributions of the K6 total scores from NHIS, NSDUH, BRFSS, and CSLC on a logarithmic scale. All the K6 distributions showed a linear pattern in parallel, except at their lower end. Specifically, K6 distributions for the NHIS, BRFSS, and CSLC deviate upward from the exponential pattern at the score of 0 and at 24 pointsBack to article page
