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 AND

objectiveNomegestrol acetate (NOMAC)/17β-estradiol (E2) is a monophasic oral contraceptive that contains a progesterone-derived progestogen (NOMAC), and E2, a bio-identical estrogen. The primary objective of this thorough QT/QTc study was to investigate whether once-daily administration of therapeutic (2.5/1.5 mg) and supratherapeutic (12.5/7.5 mg) doses of NOMAC/E2 were associated with prolongation of the mean Fridericia-corrected QT (QTcF) interval in electrocardiograms at steady-state concentrations of NOMAC/E2 versus placebo. The co-primary objective was to establish assay sensitivity after a single dose of moxifloxacin (positive control).

methodsThis was a randomized, double-blind, parallel-group trial comparing 2.5/1.5 mg of NOMAC/E2 (therapeutic dose), 12.5/7.5 mg of NOMAC/E2 (supratherapeutic dose), placebo, and moxifloxacin 400 mg. Double-blind study medication was administered from day -1 to 14. Healthy women aged 18-50 years were randomized.

resultsThe largest time-matched mean QTcF difference compared with placebo for the therapeutic dose of NOMAC/E2 was 1.6 ms, with an upper limit (UL) of a one-sided 95% confidence interval (CI) of 5.2 ms, and 3.1 ms with an UL 95% CI of 7.0 ms for the supratherapeutic dose. The UL for the time-matched QTcF differences compared with placebo were below the 10 ms threshold defined in the ICH E14 guideline for all time points, both for the therapeutic and the supratherapeutic dose. For moxifloxacin, assay sensitivity was demonstrated.

conclusionsThis thorough QT/QTc study showed that therapeutic and supratherapeutic doses of NOMAC/E2 were not associated with clinically relevant QTc interval prolongation in healthy women after a 2-week period of dosing.
