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

QTc prolongation has been associated with torsades de pointes (TdP) and also with other cardiac diseases. We investigated the effect of ipatasertib, a selective serine/threonine kinase (AKT, protein kinase B) inhibitor, on preclinical models of QTc prolongation as well as across two clinical studies. Preclinical in vitro studies suggested that ipatasertib and its metabolite, M1, were unlikely to inhibit human Ether-à-go-go-Related Gene (hERG) channels at the clinically relevant dose. However, clinical evaluation of ipatasertib and its metabolite in the first-in-human study PAM4743g suggested a mild prolongation of the QTc interval, but the effect was delayed, where the maximum change from baseline QTc seemed to occur 2-4 h after time to maximum drug exposure (T
