Results of the best multivariable* Poisson regression model for explaining history of falls in glaucoma patients

Characteristic IRR 95% CI P-value
Mediolateral STD during translational stimulus, per 1 Nm increase 1.85 1.30 – 2.63 0.001
Age, per 1 year older 1.03 0.99 – 1.07 0.162
Gender, female 3.29 1.53 – 7.07 0.002
BMI, per 1 kg/m2 higher 1.00 0.91 – 1.09 0.953
Binocular MS, per 1 dB lower 1.04 0.90 – 1.20 0.575
Binocular visual acuity, per 0.1 logMAR higher 0.25 0.01 – 5.79 0.389
Overall STD in dark field condition, per 1 Nm increase 1.02 0.86 – 1.20 0.849

IRR = incidence-rate ratio; CI = confidence interval; STD = standard deviations of the torque moments; Nm = Newton meter; BMI = body mass index; kg/m2 = kilogram per square meter; MS = mean sensitivity; dB = decibel; logMAR = logarithm of the minimum angle of resolution.

*

Multivariable model was adjusted for age, gender, BMI, severity of visual field defect, best-corrected binocular visual acuity, and STD on dark field.
