The potential risk factors of cortical visual impairment following cerebral angiography: a retrospective study.

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
backgroundCortical visual impairment is an uncommon complication after cerebral angiography with an incidence of 0.3%-1.0%. Here we would like to investigate and discuss the potential risk factors of cortical visual impairment after cerebral angiography.
methodsBased on the presence of post-operative cortical visual impairment, 4,528 patients who received cerebral angiography were split into two groups. The relevant risk factors were compared and analyzed between the groups.
resultsIn the patient cohort, 11 cases exhibited post-operative cortical visual impairment (0.24%). In particular, seven patients presented with blurred vision and four presented with binocular blindness. Visual sensation of these patients recovered after the treatment. Our univariate analysis revealed that differences in age, weight, sex ratios, proportions of patients with hypertension, diabetes and hyperlipemia, and operation time were not statistically significant between the two groups (
conclusionClinically, cortical visual impairment following cerebral angiography typically presented as blurred vision or complete blindness. We have identified the dosage of contrast medium as the most critical independent risk factor based on our study. Preventive strategies need to be implemented to avoid post-operative cortical visual impairment in this regard.
