The average serum levels for both testosterone and estradiol by MG dropout severity are shown in
Table 4. The median testosterone levels for MG dropout gradings of 1, 2, 3, and 4 were 21.06, 19.36, 21.70, and 20.06 ng/dL, respectively (
KW = 9.23,
df = 3,
P = 0.03). Post hoc pairwise comparisons showed significant differences in testosterone levels between the MG dropout scores of 1 and 4 (
KW = 9.22,
P = 0.002) and between scores 2 and 4 (
KW = 6.31,
P = 0.01). The median estradiol levels for MG dropout gradings of 1, 2, 3, and 4 were 8.15, 10.4, 8.51, and 9.35 pg/mL, respectively (
KW = 2.24,
df = 3,
P = 0.53). As shown in
Table 5, the median testosterone levels for MG expressibility scores of 0, 1, 2, and 3 were 20.94, 18.78, 27.12, and 24.01 ng/dL, respectively (
KW = 5.25,
df = 3,
P = 0.15). Likewise in
Table 5, the median estradiol levels for MG expressibility scores of 0, 1, 2, and 3 were 9.73, 8.51, 9.05, and 9.46 pg/mL, respectively (
KW = 1.37,
df = 3,
P = 0.71). As shown in
Table 6, the median testosterone levels for meibum quality gradings of 0, 1, 2, 3, and 4 were 20.73, 22.70, 18.35, 26.99, and 26.38 ng/dL, respectively (
KW = 7.21,
df = 4,
P = 0.13). Also in
Table 6, the median estradiol levels for meibum quality gradings of 0, 1, 2, 3, and 4 were 9.64, 8.03, 11.28, 14.54, and 8.08 pg/mL, respectively (
KW = 8.23,
df = 4,
P = 0.08).
