Population-based methods for estimating the number of men who have sex with men: a systematic review.

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
The objective of this systematic review was to summarise population-based methods (i.e. methods that used representative data from populations) for estimating the population size of men who have sex with men (MSM), a high-risk group for HIV and other sexually transmissible infections (STIs). Studies using population-based methods to estimate the number or percentage of MSM or gay men were included. Twenty-eight studies met the inclusion criteria. Seven studies used surveillance data, 18 studies used survey data, and six studies used census data. Sixteen studies were conducted in the US, five were conducted in European countries, two were conducted in Canada, three were conducted in Australia, one was conducted in Israel, and one was conducted in Kenya. MSM accounted for 0.03-6.5% of men among all studies, and ranged from 3.8% to 6.4% in the US, from 7000 to 39100 in Canada, from 0.03% to 6.5% in European countries, and from 127947 to 182624 in Australia. Studies using surveillance data obtained the highest estimates of the MSM population size, whereas those using survey data obtained the lowest estimates. Studies also estimated the MSM population size by dimensions of sexual orientation. In studies examining these dimensions, fewer people identified as MSM than reported experience with or attraction to other men. Selection bias, differences in recall periods and sampling, or stigma could affect the estimate. It is important to have an estimate of the number of MSM to calculate disease rates, plan HIV and STI prevention efforts, and to allocate resources for this group.
