Effect of severe contralateral carotid stenosis or occlusion on early and late outcomes after carotid endarterectomy.
Article in Annals of surgical treatment and research, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeWe aimed to compare clinical outcomes after carotid endarterectomy (CEA) between Korean patients with and without severe contralateral extracranial carotid stenosis or occlusion (SCSO).
methodsBetween January 2004 and December 2014, a total of 661 patients who underwent 731 CEAs were stratified by SCSO (non-SCSO and SCSO groups) and analyzed retrospectively. The study outcomes included the occurrence of major adverse cardiovascular events (MACE), defined as stroke or myocardial infarction, and all-cause mortality during the perioperative period and within 4 years after CEA.
resultsThere were no significant differences in the incidence of MACE or any individual MACE manifestations between the 2 groups during the perioperative period or within 4 years after CEA. On multivariate analysis to identify clinical variables associated with long-term study outcomes, older age (hazard ratios [HRs], 1.06; 95% confidence intervals [CIs], 1.03-1.09; P < 0.001) and diabetes mellitus (HR, 1.71; 95% CI, 1.14-2.57; P = 0.010) were significantly associated with an increased risk of MACE occurrence, while preexisting SCSO was not associated with long-term incidence of MACE and individual MACE components. Kaplan-Meier survival analysis showed similar MACE-free (P = 0.509), overall (P = 0.642), and stroke-free (P = 0.650) survival rates in the 2 groups.
conclusionThere were no significant differences in MACE incidence after CEA between the non-SCSO and SCSO groups, and preexisting SCSO was not associated with an increased risk of perioperative or long-term MACE occurrence.
