Knowledge of PEP and PrEP among people living with HIV/aids in Brazil.
Article in BMC public health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 1 of them a synthesis that pooled 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.
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
backgroundPre-Exposure Prophylaxis (PrEP) and Post-Exposure Prophylaxis (PEP) are key to preventing sexual transmission of HIV, whose sexual partners are at high risk of acquiring HIV. We aimed to determine the factors associated with PrEP and PEP's knowledge as secondary prevention among people living with HIV/AIDS.
methodCross-sectional analytical study carried out among people living with HIV/AIDS treated at five specialized services in the city of Ribeirão Preto, São Paulo, Brazil. Data were collected from July 2016 to July 2017. Individual interviews were conducted. We used multivariable logistic regression to determine factors associated with knowing PrEP and PEP.
resultsOf the 397 participants, 140 (35.26%) were heterosexual women aged 40 to 49 years (36.2%).Participants with less than 11 years of study (adjusted odds: 0.29; 95% CI: 0.13-0.60); who did not have a low viral load or did not know their viral load (adjusted odds: 0.29; 95% CI: 0.09-0.83) and those with casual partners (adjusted odds: 0.29; 95% CI: 0.09-0.83) were less likely to know about the PrEP. MSM (adjusted odds: 2.88; 95% CI: 1.59-5.3) and those who used alcohol during sexual intercourse (adjusted odds: 1.7; 95% CI: 1.0-2.8) were more likely to know about the PEP.
conclusionsThe knowledge about PEP and PrEP is low in Brazil. This may undermine secondary prevention efforts. Educational interventions to raise awareness of these prevention methods are needed among people living with HIV and who have HIV-negative sexual partners.
