Optical coherence tomography evaluation results. Figure shows plots of estimated marginal means of GCL thickness sectors [average (AVG), superior (S), supero‐nasal (SN)] from LMM in controls and AD for each age decade and error bars representing SE. In particular, β coefficients for the control group: GCL, AVG: β
60–69 years = −12.2 (95% CI = −17.6 to −6.7); β
70–79 years = −9.6 (95% CI = −14.8 to −4.3); β
≥80 years = −14 (95% CI = −20 to −8). GCL, S: β
60–69 years = −12.7 (95% CI = −18.2 to −7.2); β
70–79 years = −11.5 (95% CI = −16.8 to −6.2); β
≥80 years = −15.5 (95% CI = −21.6 to −9.4). GCL, SN: β
60–69 years = −13.3 (95% CI = −19.6 to −7); β
70–79 years = −11 (95% CI = −17.1 to −5); β
≥80 years = −15.2 (95% CI = −22.2 to −8.3). β coefficients for AD group: AVG, GCL: β
60–69 years = −4.1 (95% CI = −10.1 to 1.8); β
70–79 years = −3.5 (95% CI = −8.2 to 1.1); β
≥80 years = 5.4 (95% CI = −10.5 to −0.3). AVG, average; GCL, Ganglion cell layer; S, superior; SN, supero‐nasal.
