Severe drug induced acute hepatitis associated with use of St John's wort (Hypericum perforatum) during treatment with pegylated interferon α.
Article in BMJ case reports, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
A 61-year-old woman with chronic hepatitis C received peginterferon α 180 μg/week, and obtained undetectable qualitative hepatitis C virus (HCV) RNA (lower limit of detection 50 IU/ml) after 8 weeks of treatment. Shortly thereafter aminotransferase values greatly increased (>20 × upper limit of normal) and did not decline after treatment suspension. The patient admitted taking St John's wort (Hypericum perforatum) for depressed mood, recommended by a friend, during the preceding 6 weeks. Liver function tests continued to worsen and international normalised ratio (INR) prolongation developed; the patient was hospitalised. Test for antinuclear antibody was positive (1:320) and treatment with methylprednisolone was started; bilirubin and aminotransferase levels slowly declined, though a new flare occurred when steroids were tapered. After 6 months of prednisone treatment, the liver function tests returned to baseline levels. The combination of peginterferon α and St John's wort resulted in a severe acute hepatitis in this patient. Patients should be advised of this potential toxic effect of this herbal remedy.
