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

backgroundThis study investigates the willingness of older adults to participate in a hypothetical deprescribing clinical trial.

methodsWe conducted an online survey of adults aged 65+ years in Australia and the United States. Participants rated their willingness to enroll in a deprescribing trial, responding to the statement, "Research is conducted to assess the safety and effectiveness of stopping medicines. Imagine your doctor made you aware of a research trial aiming to help people stop one or more of their medicines. To what extent would you be willing to enroll in the study?" on a 6-point Likert scale with "Not at all willing (1)" and "Extremely willing (6)" as the scale anchors. Participants provided a brief free-text explanation. We dichotomized the outcome variable as willing (scores 4-6) and unwilling (scores 1-3) to enroll and conducted descriptive analyses, chi-square tests, and univariate and multivariate logistic regression models. Free-text responses were analyzed using content analysis, with descriptive statistics summarizing themes.

resultsThere were 2334 participants in the quantitative analysis and 2237 participants in the content analysis. Most were willing (n = 1705, 73%) rather than unwilling (n = 629, 27%) to enroll in a deprescribing trial (p < 0.001, 95% CI 0.712, 0.748). Over one-half of participants (n = 1252, 56%) expressed the "positive about deprescribing trials" domain, with Australian participants more likely to do so (AU 666 [60%] vs. US 586 [52%], p < 0.001). Participants (n = 1047, 47%) frequently reported at least one theme of the "concerns and hesitations" domain (n = 669, 30%) with US participants more frequently expressing negative views (US 273 [24%] vs. AU 211 [19%], p = 0.002) and reporting the "mistrust" theme (US 74 [7%] vs. AU 35 [3%], p < 0.001).

conclusionsOlder adults showed a willingness to engage in deprescribing trials, though concerns may affect enrollment. Clear communication of risks and benefits could support recruitment.
