Analyses were performed with linear mixed models (LMMs), which allowed optimal use of all the data and applied comprehensive adjustment to the results. A wide selection of potential predictors for SLT efficacy were first analyzed separately regarding their association with intraocular pressure reduction (IOPR). Predictors meeting a threshold of p<0.1 were then included in a multivariable candidate model, which was refined through manual stepwise backwards selection until only significant variables (p<0.05) remained. Thereafter, other variables of interest were evaluated in this model.</p><p><strong>Main outcome measure: </strong>Mean IOPR 1-6 months after SLT.</p><p><strong>Results: </strong>The 360/high protocol remained the most efficacious SLT variant after adjustment for predictors (coefficient estimate (CE) 360/high 2.0, 360/standard 0.9, and 180/high -0.1, with 180/standard as the reference; p<0.001). Higher baseline IOP was a positive predictor for both absolute IOPR (CE 0.35; p<0.001), and relative IOPR (CE 0.72; p<0.001). A larger IOPR from the prior SLT (CE 0.18; p=0.004), as well as IOPR in the contralateral eye (CE 0.57; p<0.001) were also highly significant positive predictors. Conversely, the present analyses suggest that SLT efficacy is diminished by pseudoexfoliations (CE -0.69; p=0.02), the number of prior SLTs (CE -0.54; p=0.004), and increased corneal thickness (CE -0.01; p<0.002). Consultants/specialists and residents achieved similar SLT results, but individual surgeon performance mattered (p=0.003) as well as if the surgeon used the dominant hand (CE 0.35; p=0.050). However, age, glaucoma medication, cataract surgery, anterior chamber angle pigmentation, inflammatory symptoms, or postoperative anterior chamber flare had no correlation with SLT efficacy.</p><p><strong>Conclusions: </strong>The 360/high protocol remained the most effective and reliable technique after adjustment for multiple predictors. No evidence was found to advise against 360/high SLT for any particular group of patients.
