1 · What the graph read from it

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.

2 · The registry

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 objective of this study was to examine the variation in practice patterns and associated outcomes for carotid endarterectomy (CEA) within the Southern California Vascular Outcomes Improvement Collaborative (So Cal VOICe), a regional quality group of the Vascular Quality Initiative.

methodsAll cases entered in the CEA registry by the So Cal VOICe were included in the study.

resultsFrom September 2010 through September 2015, 1,110 CEA cases were entered by 9 centers in the So Cal VOICe. Six hundred seventy-seven patients (61%) were male with mean age of 73 years. Nine hundred eighty-eight (89%) were hypertensive, 655 (59%) were prior or current smokers, 389 (35%) were diabetics, and 233 (21%) had coronary artery disease. Eight hundred twenty-one (74%) patients were asymptomatic (no history of ipsilateral neurologic event). The percentage of asymptomatic patients varied across the 9 centers from 57% to 91%. Preoperatively, 344 (31%) underwent cardiac stress test, center variation 13-75%, 500 (45%) underwent only duplex, center variation 11-72%. Intraoperatively, 600 (54%) underwent routine shunting, whereas 67 (6%) were shunted for an indication, and 444 (40%) were not shunted. Wound drainage was used in 422 (38%) cases, center variation 2-98%. Completion imaging by duplex and/or angiogram was performed in 766 (69%) cases, center variation 0-100%. Postoperatively, 11 (1%) patients had a new ipsilateral postoperative neurologic event, center variation 0-1.3%, 6 (0.5%) had a postoperative myocardial infarction, center variation 0-1.3%, and 8 (0.7%) required return to operating room for bleeding, center variation 0-1.3%.

conclusionsDespite wide variation in practice patterns surrounding CEA in the So Cal VOICe, postoperative complications were uniformly low. Further work will focus on identifying practices that can be modified to improve cost-effectiveness while maintaining excellent outcomes.
