Human polyomavirus KI, WU, BK, and JC in healthy volunteers.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Despite the growing importance of infections caused by the human polyomaviruses (HPyVs), information about their transmission, pathogenesis, and epidemiology is scarce. The objective of this work was to evaluate the excretion and distribution of HPyV (HPyV1-HPyV4 [former BKPyV, JCPyV, KIPyV, and WUPyV, respectively]) among asymptomatic individuals from different geographic regions in Brazil, in order to verify the existence of distinct epidemiologic patterns among the Brazilian population. Saliva samples from 889 healthy volunteers living in nine locations in Brazil were analyzed by real-time polymerase chain reaction (PCR) to detect HPyV1-4. Among 889 participants, 346 (39%) had evidence of infection with one or more HPyV species: 127 (14.3%) had HPyV1 only; 70 (7.9%) had HPyV3 only; 60 (6.7%) had HPyV4 only, and 25 (2.8%) had HPyV2 only. Coinfections were detected in 64 participants (7.3%). Although HPyV excretion was detected in samples from all locations, the frequency and distribution of viral species varied significantly. The epidemiologic findings presented demonstrate that the four HPyV species studied are circulating in five geographic regions of Brazil. Salivary excretion of these viruses appears common among healthy Brazilians. The distribution of viral species varies considerably between regions as well as within regions.
