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

purposeTo investigate whether institutionalization is associated with the use of antiepileptic drugs (AEDs) and to compare the association between use of AEDs and psychotropics in community-dwelling and institutionalized elderly, after adjustment for age, sex and co-morbidity (i.e. number of other drugs).

methodsWe analyzed data on age, sex and dispensed drugs for individuals aged ≥65 years registered in the Swedish Prescribed Drug Register from July to September 2008, record-linked to the Swedish Social Services Register (n = 1,345,273: 1,258,565 community-dwelling and 86 708 institutionalized elderly). Multivariate logistic regression analysis was used to analyze whether institutionalization and use of psychotropics (i.e. antipsychotics, anxiolytics, hypnotics/sedatives and antidepressants) were associated with the use of AEDs.

resultsAEDs were used by 2% of the community-dwelling and 9% of the institutionalized elderly. The most commonly used AEDs were carbamazepine, gabapentin, pregabalin, valproic acid and lamotrigine. Institutionalization was strongly associated with AED use (OR(adjusted) = 3.98; 95% CI 3.86-4.10). In community-dwelling elderly, AED use was associated with an increased probability of use of all types of psychotropics. However, among institutionalized elderly, the associations between use of AEDs and psychotropics showed a mixed pattern.

conclusionsAED use seems to be common among Swedish institutionalized elderly, and institutionalization is a strong determinant of AED use. Our results may also indicate an off-label prescribing of AEDs as an alternative to psychotropics in the institutional setting. This finding needs to be confirmed by others and evaluated with respect to outcomes of this treatment in institutionalized elderly.
