The influence of renal function on surgical outcomes of vitrectomy in patients with proliferative diabetic retinopathy.

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
Purpose: To investigate the influence of renal function on the surgical outcomes of vitrectomy in patients with proliferative diabetic retinopathy (PDR). Methods: A secondary analysis was conducted on data from a retrospective cohort study. Results: A total of 128 eyes with PDR that underwent pars plana vitrectomy (PPV) and were followed up for at least 2 years were enrolled, including 65 eyes in the impaired renal function (IRF) group and 63 eyes in the normal renal function (NRF) group. No significant between-group differences were observed in the proportion of cataract surgery (p = 0.722), intraoperative retinal photocoagulation (p = 0.476), gas tamponade (p = 0.932), silicone oil tamponade (p = 0.254), retinal dialysis and/or iatrogenic retinal breaks (p = 0.447), and 23- or 25-gauge (G) microincision vitrectomy surgery (MIVS) (p = 0.160). Similarly, intergroup comparisons showed no significant differences in the proportion of reoperation (p = 0.883), postoperative vitreous hemorrhage (VH) and/or retinal detachment (RD) (p = 0.919), postoperative neovascular glaucoma (NVG) (p = 0.600), and postoperative diabetic macular edema (DME) (p = 0.794). Notably, the IRF group had worse baseline best corrected visual acuity (BCVA) (p = 0.039) and showed greater BCVA improvement at 3 months (p = 0.008), 6 months (p = 0.047), 1 year (p = 0.007), 2 years (p = 0.003), 3 years (p = 0.009), and 4 years (p = 0.024) after surgery. However, there was no significant difference in postoperative BCVA between the two groups at each follow-up time (all p > 0.05). Conclusions: Renal insufficiency does not adversely affect the surgical outcomes of PPV in patients with PDR.
