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

purposeThis paper compares younger (aged 18-39; n=197) and older (ages 50+; n=53) MSM to determine their familiarity with PrEP, willingness to learn more about PrEP, perceptions of stigma relating to PrEP use, and perceptions of barriers to PrEP adoption.

methodsA purposive sample of diverse MSM completed 15-minute questionnaires. Younger and older MSM were compared using Student's t-tests and odds ratios for bivariate analyses, and multivariate logistic regression and multiple regressions for analyses controlling for key demographic characteristics.

resultsCompared to younger MSM, older MSM were more aware of PrEP, more likely to know another PrEP user, less interested in learning more about PrEP, and more averse to using existing resources to learn more about PrEP. Older men perceived less stigma relating to PrEP and fewer obstacles needing to be overcome in order to give serious consideration to PrEP adoption. These differences remained when race, educational attainment, sexual orientation, and HIV serostatus were controlled.

conclusionsThere is a "good news/bad news" situation with respect to older MSM and PrEP. They were more aware of PrEP, less likely to associate stigma with PrEP use or PrEP users, and anticipated fewer barriers to PrEP adoption. They were also less interested than their younger counterparts in learning more about PrEP and expressed less comfort using existing sources of information to learn more about PrEP. Age-appropriate PrEP educational campaigns are advisable in order to reach older MSM and encourage more of them to consider PrEP adoption.
