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
backgroundAntiepileptic drug monotherapy is the mainstay of treatment for epilepsy; however, the efficacy of different antiepileptic drugs in reducing the incidence of seizure-related hospitalization among older adults, who are at higher risk of developing epilepsy compared to their younger counterparts, has not been examined. PURPOSE: The objective of the present study was to compare the rate of seizure-related hospitalization among older adults on levetiracetam compared to different antiepileptic drugs (AEDs). PATIENTS AND
methodsThis was a retrospective cohort study of older adults (≥60 years) in two tertiary care hospitals. Patients who are 60 years of age and older, have a confirmed diagnosis of epilepsy, and are taking a single and the same antiepileptic drug for at least 36 months were included. The patients were followed up for 24 months after 12 months of treatment with no incidence of seizure-related hospitalization via their health records. Multiple Poisson regression with robust error variance was used to estimate the relative risk of hospitalization for patients on levetiracetam compared to different antiepileptic drugs controlling for age, gender, number of prescription medications, dosage strengths, and Charlson Comorbidity Index (CCI) score.
resultsOne hundred and thirty-six patients met the inclusion criteria and were included in the study. The recruited patients were on one of the following four antiepileptic drugs: carbamazepine (n=44), levetiracetam (n=39), phenytoin (n=31), and valproic acid (n=22). Patients on levetiracetam were more than twice as likely to be hospitalized due to seizures within the 24 months of follow-up compared to their counterparts on other AEDs (RR=2.76, 95% CI=1.16-6.53,
conclusionThis study suggests that older adults on old generation AEDs such as phenytoin, carbamazepine, and valproic acid appear to have a lower risk of seizure-related hospitalization compared to their counterparts on levetiracetam.
