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
backgroundThe purpose of this study was to compare the frequency of microembolic brain infarcts after direct navigation method versus exchange method in carotid artery stenting and vertebral artery origin angioplasty. METHODS AND MATERIAL: This is a prospective study conducted at Shiraz University of Medical Sciences in southern Iran. Consecutive patients undergoing "carotid angioplasty and stenting" and "vertebral artery origin stenting" were randomly assigned into two groups with "direct navigation method" and "exchange method." Subsequently, postprocedural magnetic resonance imaging (MRI) including diffusion weighted imaging and apparent diffusion coefficient were obtained within the first 24 hours after completion of the procedure.
resultsIn total, 89 patients were recruited (67% male, mean age: 72 years). Cases comprised of 38 left internal carotid arteries (ICAs), 38 right ICAs, 6 left vertebral artery origin, and 7 right vertebral artery origin. Forty patients underwent exchange method, while 49 underwent direct navigation method. There was only one clinical stroke that occurred in "exchange method" group. Fifteen patients (37.5%) in exchange group and 23 patients (46.9%) in direct navigation group developed diffusion restricted lesions. In exchange group, 13 patients (32.5%) had at least one diffusion restricted lesion ipsilateral to the target vessel, and three patients (7.5%) had at least one diffusion restricted lesion contralateral to the target vessel. In direct navigation group, these measures were 19 (38.8%) and 9 (18.4%). However, no statistically significant intergroup differences were observed. The only significant difference was bilateral infarct percentile, which was more common in the direct navigation method (0.032).
conclusionDiffusion restricted lesions were more common in the direct navigation method, both ipsilateral and contralateral to the target vessel, and in both carotid and vertebral artery study subgroups. However, differences were not statistically significant.
