The role of endovascular expertise in carotid artery stenting: results from the ALKK-CAS-Registry in 5,535 patients.
Article in Clinical research in cardiology : official journal of the German Cardiac Society, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
purposeSeveral scientific committees have proposed an accentuation of operator minimal requirements before accreditation for carotid artery stenting is granted. The current study aims to identify potential effects from increasing site experience on periprocedural safety and outcome of carotid artery stenting (CAS).
methodsBetween 1996 and December 2009, 5,535 procedures have been entered into the prospective, controlled ALKK-CAS-Registry. The total cohort was divided in four subgroups according to the consecutive patient order at each participating center: patients 1-49 (n = 1,485), 50-99 (n = 1,118), 100-199 (n = 1,521) and ≥200 (n = 1,411).
resultsThe median age of all patients was 71 years; 52.8 % had a symptomatic carotid stenosis. A decline in the rates of in-hospital major stroke (2.1, 1.9, 1.6, 0.9, p for trend 0.014) and of ipsilateral strokes (3.1, 2.4, 2.5, 1.6 %, p for trend 0.019) was substantiated with increasing site experience. This significant trend was preserved in the combined rate of major stroke and death (4.0, 3.2, 3.4, 2.4 %, p for trend 0.034). Apart from CAS experience, improvements in CAS technique, a decreasing number of symptomatic patients and an increasing number of procedures under embolic protection (each p for trend <0.05) might have contributed to these results.
conclusionsThe results show a gradual reduction of in-hospital stroke rates with increasing center experience. Extensive supervision of CAS learners and further promotion of proctorship programs seem to be essential.
