(A) Proportion of DED patients (n = 52) with aqueous deficiency dry eye (Schirmer test <5 mm) or evaporative dry eye (NI-TBUT <6 s). (B,C) Proportion of Cluster-1 or Cluster-2 dry eye patients with aqueous deficiency dry eye or evaporative dry eye, respectively. The subject numbers analyzed for this diagram was 52. In all three panels, the numbers outside the circles are patients who did not qualify as aqueous, or evaporative or mixed.
