Distribution and impact of age in patients with implantable cardioverter-defibrillators regarding early complications and 1-year clinical outcome: results from the German Device Registry.

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
backgroundPatients receiving implantable-cardioverter-defibrillators (ICD) in clinical practice are often older or younger than in clinical trials. Whether older patients benefit from ICD-therapy in a similar way as younger patients is under debate. The objective of this study was to provide real-world data regarding outcomes with respect to age in a large cohort in the German Device Registry.
methodsWithin the registry data from 50 German centers were collected between January 2007 and February 2014.
resultsOur analysis included 3239 ICD patients representing a group of young (28%; group I: < 58 years), intermediate aged (50%; group II: 58-74 years), and elderly patients (22%; group III: 75-92 years). Intergroup comparison of all groups was performed followed by individual comparison vs. group II serving as age-reference group. Procedure-related complications did not differ between all groups. Analysis of the primary endpoint, 1-year all-cause mortality, revealed an increased mortality in the elderly and a decreased mortality in the young cohort vs. the reference group II (group I 2.1%, group II 6.2%, group III 13.2%; p < 0.001). While all-cause rehospitalizations did not differ, we observed a difference in reported device revisions showing more device revisions required in younger patients (group I 8.9%, group II 6.8%, group III 4.0%; p = 0.001).
conclusionsOne-year mortality was doubled in elderly ICD patients probably due to non-cardiac causes. These results further underpin the need for re-evaluating the primary prevention ICD indication in octo- and nonagenarians. Young patients show lower mortality rates but seem to bear higher risk of device-related complications, which highlights the need for improved measures to reduce device-related complications in the young.
