Male condom and dual protection use by adolescent men in Brazil.
Article in Revista de saude publica, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveTo assess the use of male condoms and dual protection by Brazilian adolescent men, as well as their associated aspects.
methodsA database from the Study of Cardiovascular Risks in Adolescents (ERICA) was used for this national cross-sectiotabelnal school-based research. The sample included adolescents of both sexes, aged between 12 and 17 years old, selected through cluster sampling in 2014 (n = 75,060). This study analyzed information from adolescent men who reported having had sexual intercourse (n = 12,215). The dependent variables were the use of male condoms and the use of dual protection (simultaneous use of male condoms and oral hormonal contraceptives) in the last sexual intercourse. Data were analyzed using univariate and multiple logistic regression.
resultsMost adolescents used a male condom in the last sexual intercourse, while the use of double protection was quite low. The use of male condoms, reported by 71% (95%CI 68.7-73.1), was positively associated with age, living with both parents, and having used alcohol in the previous 30 days. The use of double protection, reported by 3.6% (95%CI 2.8-4.5) was positively associated with age and studying in a private school, as well as negatively associated with tobacco use in the previous 30 days.
conclusionsThe wide difference shown in the proportion of condom or dual protection use in the last sexual intercourse draws attention to the different logics that govern juvenile sexual relations. The low proportion of dual protection use may be a reflection of men's lack of knowledge about a function that has historically been attributed to women, which is contraception. Thus, one must deconstruct such dichotomy that the sphere of sexuality is of the domain/interest of men, while that of reproduction concerns only women.
