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

Nationwide analyses of drug use can provide a prevalence estimate of the underlying disease and can help in understanding the characteristics of treatment. This study aimed for such analyses regarding the utilization of antiepileptic drugs (AED) for epilepsy in Germany. In 2009, all 4,115,705 AED prescriptions of all German patients with statutory health insurance (70,011,508 persons) were retrospectively analyzed. The IMS(®) LRx database served as data source, which accesses nationwide pharmacy data centers processing all German prescription data. To establish the age and sex-specific percentage of patients taking AED because of epilepsy, we used a second database, Disease Analyzer(®), which covered a representative sample of the German population (7.2 million patients) and contained ICD10 codes alongside with prescription data. The period prevalence of patients taking AED because of epilepsy was 9.1/1,000 (children/adolescents: 5.2/1,000; elderly: 12.5/1,000). Of the patients, 83.1 % took at least one of four AED: valproate (29.8 %), carbamazepine (26.4 %), lamotrigine (21.4 %), and levetiracetam (16.9 %). Oxcarbazepine and sultiame were popular with pediatricians. Elderly patients frequently received phenytoin and primidone. More than half of the patients were treated by family physicians; 68 % took AED in monotherapy and 7.9 % received >2 AED (children/adolescents: 12.5 %). The costs for AED prescribed for epilepsy amounted to €285.1 Mio (median AED costs/patient: €158/a). The German 2009 prevalence of epileptic patients taking AED was 9.1/1,000. Family physicians cared for the majority of patients. Prevalence and prescribing patterns changed with age. Costs of AED against epilepsy added up to 1 % of total medication costs in Germany.
