Combined phacoemulsification and vitrectomy for proliferative diabetic retinopathy: an increased risk of early recurrence but not long-term neovascular glaucoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo compare the long-term incidence of recurrent vitreous hemorrhage(VH) and neovascular glaucoma (NVG) in patients with proliferative diabetic retinopathy (PDR) undergoing pars plana vitrectomy (PPV) alone versus combined PPV and phacoemulsification (PPV&P).
methodsThis large, single-center, retrospective cohort study analyzed 548 eyes (137 PPV&P, 411 PPV-alone) with a minimum 12-month follow-up. Kaplan-Meier survival analysis and multivariable Cox proportional hazards regression models were used to compare outcomes and identify independent predictors for complications within a 2-year follow-up period. A supplementary propensity score-matched (PSM) analysis was also performed to confirm the findings.
resultsOver the entire follow-up, the overall incidence of recurrence and NVG did not differ significantly between the groups. However, multivariable Cox regression analysis for the first two years revealed that PPV-alone was a significant protective factor against recurrence (adjusted Hazard Ratio [aHR], 0.61; 95% CI, 0.40-0.92), while severe preoperative traction was a major risk factor (aHR, 2.24; 95% CI, 1.39-3.60). For NVG development within two years, the surgical approach was not a significant factor. Instead, severe preoperative traction (aHR, 5.88; 95% CI, 1.67-20.68) and older age (aHR, 1.06; 95% CI, 1.01-1.11) were the primary independent risk factors.These findings were confirmed in a 1:1 age-matched PSM cohort.
conclusionCombined PPV with phacoemulsification is associated with an increased risk of recurrence within the first two postoperative years but does not increase the risk of neovascular glaucoma. The severity of baseline proliferative disease, particularly the degree of traction, is a more critical determinant of postoperative complications than the surgical strategy regarding the lens. This supports tailoring the surgical approach based on individual patient cataract status and retinal pathology.
