HIV testing is associated with increased knowledge and reductions in sexual risk behaviours among men in Cape Town, South Africa.

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
HIV testing benefits those who test positive, allowing them to receive treatment, but the benefits for those who test negative remain controversial. We evaluated the impact of testing on HIV knowledge and sexual risk among men in South Africa. Men were recruited from townships outside Cape Town and completed a survey that assessed testing history, knowledge, and sexual behaviours. Among the 820 participants, 516 (63%) reported being tested (82% tested negative, 6% tested positive, and 12% unknown). Compared to those who had never been tested for HIV, men who tested for HIV were more knowledgeable about HIV transmission, but did not differ on sexual risk behaviour. Knowledge moderated the effect of testing on sexual risk such that men reported fewer sexual partners (incidence rate ratio (IRR) = 0.91, 95% CI = 0.84, 0.98) and fewer unprotected anal sex events (IRR = 0.81, 95% CI = 0.66, 1.00) if they had been tested for HIV and were knowledgeable about HIV transmission. For men testing HIV-negative, knowledge predicted fewer sexual risk behaviours. Previous HIV testing is associated with enhanced knowledge, which moderates sexual risk behaviour among South African men living in Cape Town. Results suggest that HIV testing may increase knowledge and lead to reductions in sexual risk even when results are negative.
