Evaluation of lacrimal drainage system in Pseudoexfoliation syndrome.

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 evaluate the prevalence of the obstruction of lacrimal drainage system (LDS) in patients with pseudoexfoliation (PXF) syndrome. MATERIALS AND
methodsThis cross-sectional study included 152 eyes of 76 consecutive patients with bilateral PXF syndrome and 170 eyes of 85 age and gender-matched controls. The LDS evaluation was performed based on dye disappearance test, slit-lamp examination, diagnostic probing, and irrigation test. The presence of punctal stenosis and canalicular obstruction were considered as the obstruction of proximal LDS; and complete or incomplete nasolacrimal duct obstruction was considered as obstruction of distal LDS. Demographic characteristics, ophthalmologic findings, and prevalence and site of obstruction of LDS were compared among the groups.
resultsThe prevalence of obstruction of LDS was higher in the PXF syndrome group when compared to controls (21.1% vs 12.2%), but the difference was not statistically significant (p = 0.061). The obstruction of proximal LDS was found to be more frequent in the PXF syndrome (17.7%) group when compared to controls (10.0%), and this difference was statistically significant (p = 0.041). There was significantly more punctal stenosis in the PXF syndrome group when compared to controls (15.1% vs 7.6%, p = 0.033). The prevalence of canalicular stenosis and obstruction of distal LDS was similar in the PXF and the control groups (p = 0.596 and p = 0.741, respectively).
conclusionThe prevalence of punctal stenosis was statistically significantly higher in the PXF syndrome group when compared to the controls. This association is probably related to increased local ocular surface inflammation which is triggered by the accumulation of PXF material.
