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

Administration of certain drugs (for example, antiarrhythmics, antihistamines, antibiotics, antipsychotics) may occasionally affect myocardial repolarization and cause prolongation of the QT interval. We performed a whole genome association study of drug-induced QT prolongation after 14 days of treatment in a phase 3 clinical trial evaluating the efficacy, safety and tolerability of a novel atypical antipsychotic, iloperidone, in patients with schizophrenia. We identified DNA polymorphisms associated with QT prolongation in six loci, including the CERKL and SLCO3A1 genes. Each single nucleotide polymorphism (SNP) defined two genotype groups associated with a low mean QT change (ranging from -0.69 to 5.67 ms depending on the SNP) or a higher mean QT prolongation (ranging from 14.16 to 17.81 ms). The CERKL protein is thought to be part of the ceramide pathway, which regulates currents conducted by various potassium channels, including the hERG channel. It is well established that inhibition of the hERG channel can prolong the QT interval. SLCO3A1 is thought to play a role in the translocation of prostaglandins, which have known cardioprotective properties, including the prevention of torsades de pointes. Our findings also point to genes involved in myocardial infarction (PALLD), cardiac structure and function (BRUNOL4) and cardiac development (NRG3). Results of this pharmacogenomic study provide new insight into the clinical response to iloperidone, developed with the goal of directing therapy to those patients with the optimal benefit/risk ratio.
