Knowledge of HIV status among men aged 20-35 years in Lusaka, Zambia: Findings from a pilot time location sampling survey in the "Yaba Guy Che" (for the guys) study.

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
objectivesWe conducted a pilot time location sampling survey with young men aged 20-35 years in Lusaka, Zambia and aimed to describe knowledge of HIV status and determine factors associated with knowledge of HIV status.
methodsHotspots where men congregate were identified in a densely populated community in Lusaka. Hotspots were grouped into five strata (betting shops; car parks/washes; bus stations/taxi ranks; churches; and markets/shopping streets) and day/times when hotspots were frequented by men were listed. Within each stratum, three hotspots were randomly selected. Subsequently, 1 day/time was randomly selected for each hotspot. Men aged 20-35 were approached for participation and data was collected between July and October 2022. We describe participation in the survey, socio-demographics, and sexual behaviours. Using logistic regression, we explored factors associated with knowledge of HIV status.
results339 men were approached, among whom 304 (90%) were eligible and 297 (98%) consenting to participate. Overall, 61% knew their HIV status. Adjusting for recruitment strata, knowledge of HIV status was similar by age (20-24: 56%; 25-29: 68%; and 30-35: 55%; p = 0.19). Among men reporting sex in the last month, men reporting no condomless sex were more likely to know their HIV status (78.2%) compared to men reporting one condomless sex partner in the past 1 month (55.5%; age-adjusted OR = 3.02; 95%CI 1.07, 8.55; p = 0.07). Knowledge of HIV status was lower among men who thought their friends were testing every 2-5 years (48%; n = 12/29) compared to those assuming that their friends tested more frequently (70.0%; adjOR = 0.28; 95%CI 0.08, 0.98; p < 0.001).
conclusionThe time location sampling survey was acceptable among men, as evidenced by high participation. Overall, 40% of young men did not know their HIV status. A hotspot-driven approach to delivering HIV testing services may prove effective at reaching men. Furthermore, time location sampling surveys should be explored as a tool to evaluate interventions targeting men.
