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

Background: Treatment-resistant schizophrenia (TRS) poses a substantial clinical challenge for which clozapine (CLOZ) is the only effective treatment. However, clinicians may hesitate to prescribe CLOZ for TRS patients with epilepsy due to its presence because CLOZ is contraindicated in patients with uncontrolled epilepsy in some countries including Japan. Case Presentation: A 36-year-old male with TRS and focal epilepsy underwent CLOZ therapy. CLOZ was initiated at 6.25 mg and gradually titrated to 250 mg over 3 months, achieving a plasma concentration of 449 ng/mL. Psychotic symptoms improved without worsening of seizure frequency or severity. Mild side effects such as drowsiness and drooling were manageable. Long-term video electroencephalography monitoring detected spike-and-wave activity centered in the frontal region, but did not detect any overt epileptic seizures. Conclusion: We report a case of TRS with comorbid epilepsy in which CLOZ therapy was both effective and safe.
