The prevalence of pharmacogenetic testing in the United States.
Article in Pharmacogenetics and genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
It is unknown how many people in the US have had pharmacogenetic (PGx) testing and whether people want to be tested. We conducted a nationally representative survey of the general US adult population to determine the prevalence of adults that have had PGx testing using a validated confidential online survey, the Non-Medical Use of Prescription Drugs Program. A weighted logistic regression was used to test health characteristics associated with PGx testing and determine those who desire to be tested. The analysis included 29 146 individuals who completed the survey, which represents approximately 260 000 000 adults in the US. The prevalence of US adults who have been PGx tested is 6.6% [95% confidence interval (CI): 6.2-7.0]. Only 32.2% (95% CI: 31.5-32.9), an estimated 79 million individuals, desired PGx testing. Adults who had or want PGx testing were more likely to be female, have higher education, be students, current or former members of the military, use medications, and have a mental health disorder. The prevalence of adults who have been PGx tested remains low in the US. There are knowledge gaps about the benefits of PGx testing that must be bridged to increase implementation.
