[Treatment reality of internal carotid artery stenosis in Germany : requirement and reality in international comparison and in light of the current S3 guidelines].
Article in Der Nervenarzt, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSevere atherosclerotic extracranial carotid artery stenosis accounts for 5-10 % of all ischemic strokes. Currently, therapeutic recommendations are undergoing changes, particularly regarding the treatment of asymptomatic stenosis. Consolidated knowledge on the indications, nationwide distribution and numbers of cases are not available. Moreover, the impact and grade of implementation of the recently published national S3 guidelines on the reality of medical treatment remain unclear.
methodsAnalysis of administrative hospital data involving the diagnosis-related groups (DRG) statistics and structured quality reports for 2010 and 2013 to evaluate the procedural therapy trends concerning operative and interventional approaches for symptomatic and asymptomatic carotid artery stenoses.
resultsIn Germany approximately 37,000 carotid endarterectomies (CEA) and approximately 5,000 carotid angioplasties with stenting (CAS) are carried out per year. Approximately 94 % of CEA and 62 % of CAS are performed in centers with more than 25 procedures per year. Only 33 % of CEA and 39 % of CAS are related to symptomatic stenosis.
conclusionMathematically, an undertreatment of symptomatic and an overtreatment of asymptomatic carotid artery stenoses become apparent. Efforts should be made to achieve inpatient medical treatment conforming to the national S3 guidelines, in particular to adequately reduce the risk of stroke recurrence in patients with atherosclerotic symptomatic carotid artery stenosis.
