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

objectiveTraumatic brain injury (TBI) is common and associated with a marked increased risk of developing epilepsy. Animal studies indicate that treatment with selective serotonin reuptake inhibitors (SSRIs) may increase the risk of epilepsy after TBI. The aim of this study was to investigate whether use of SSRIs modifies the risk of epilepsy after TBI.

methodsThis was a cohort study of 205,715 persons, who suffered a TBI in Denmark from 1996 to 2013. For each person with TBI, we matched 10 reference persons (N = 2,057,150) who were alive on the day of TBI and who had the same age and gender but had no history of TBI. We used a stratified Cox regression to calculate the relative risk of epilepsy after TBI for persons exposed to TBI, SSRI or both after adjustment for income, civil status, medical and neurological comorbidities, severe mental disease, and substance abuse.

resultsThe risk of epilepsy was 5.61 times higher for persons who used SSRI at time of TBI (adjusted Hazard Ratio (aHR): 5.61 (95% CI: 4.88; 6.45)), 3.23 times higher for persons who had a TBI but did not use SSRI at time of TBI (aHR: 3.23 (95% CI: 3.12;3.35)), and 1.31 times higher for persons who used SSRI but had no TBI (aHR: 1.31 (95% CI: 1.18; 1.45)) compared to persons unexposed to both TBI and SSRI.

conclusionsThis large population based cohort study showed that people using SSRI at the time of a TBI had higher risk of developing epilepsy compared to people not using SSRI at the time of TBI. The results are in line with those of animal studies and calls for further studies to evaluate whether the association is due to SSRIs or to the underlying disease (e.g. depression or anxiety).
