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

objectivesClozapine is the most efficacious treatment for treatment-resistant schizophrenia; however its use can be limited by intolerability. Sinus tachycardia is a common adverse event associated with clozapine use, which may lead to the premature discontinuation of clozapine. Traditionally, β blockers are used to treat clozapine-associated tachycardia, though problems with intolerability and ineffectiveness can limit their utility.

methodsIn this article, we present two cases of patients with treatment-resistant schizophrenia who developed symptomatic tachycardia associated with clozapine therapy.

resultsWe demonstrate that the novel heart rate controlling agent ivabradine can be effectively and safely used to control the heart rate and to allow for continued treatment with clozapine.

conclusionThis is the first report in the literature demonstrating that ivabradine appears to be a well tolerated agent, which should be considered as a symptomatic treatment of clozapine-induced tachycardia if the use of a β blocker fails due to a lack of response or intolerability.
