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

Purpose of researchDescribe prescribing patterns in Australian Vietnam veterans, identify CYP2C19-metabolised medications using established pharmacogenetic (PGx) resources, characterise CYP2C19 profiles of veterans and assess the potential clinical impact of these medications.Major findingsAmong 283 veterans with CYP2C19 profiles, 256 reported current medications use, with a mean prescribed medication of 5.4. Of these, 89 veterans (34.7%) were prescribed at least one medication with CYP2C19 PGx recommendation. Notably, 52 veterans (58.4%) had CYP2C19 profiles that may be at risk of therapeutic failure or adverse effects. Prescribed medications also included six CYP2C19 inhibitors and one inducer, with potential to induce phenoconversion and impact drug metabolism.ConclusionVeterans experienced high levels of polypharmacy and frequently carried CYP2C19 phenotypes associated with increased risk of therapeutic failure or adverse effects. The presence of CYP2C19 inhibitors and inducers raises the potential for phenoconversion, where CYP2C19 profiles may be placed at risk. Given their similarities to the broader older population, these findings suggest that both groups may benefit from pre-emptive PGx testing. Furthermore, ongoing monitoring of drug-gene and drug-drug interactions remains essential to optimise medication safety and efficacy in these high-risk individuals.
