A Large Scale Study of the Epidemiology and Risk Factors for the Carcinogenic Liver Fluke Opisthorchis viverrini in Udon Thani Province, Thailand
Article in Asian Pacific journal of cancer prevention : APJCP, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 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
Opisthorchis viverrini infection and cholangiocarcinoma are serious problems in South East Asia. This study aimed to find the prevalence of opisthorchiasis in various hosts in Udon Thani Province. Total fecal samples were collected from 14,766 participants. The epidemiological data collected and analysed included prevalence and intensity of infection. Odds ratios (OR) were calculated to determine the associations between cross sectional data and to predict possible risk factors. The prevalence of O. viverrini infection in Udon Thani Province averaged 15.3% (eggs per gram (epg.) = 48.9 and range; 12-1, 320), with differences between villages (range; 3.8%-79.8%). An age-dependence for infection was observed to increase from ages 25 to 50 years and then decrease for older participants. A univariate analysis identified risk parameters including age (p = 0.040; OR = 3.9 (95% CI = 1.2-7.5)), education (p < 0.0001; OR = 7.3 (95% CI = 1.8-21.6)) and eating habits (p = 0.032; OR = 1.6 (95% C = 0.5-3.7)). Interestingly, most participants were not aware of treatments such as praziquantel (p < 0.0001; OR = 3.5 (95% CI = 1.4-11.6)), had no history of parasitic treatment (p = 0.486; OR = 1.5 (95% CI = 0.5-3.5) and had eaten raw fish (p=0.04; OR = 7.4 (95% CI = 1.5-18.6)). Liver fluke infection in dogs (18.1%, epg. = 44.7, range; 32-96) was significantly higher than in cats (11.0%, epg. = 117.8, range; 44-372) (p < 0.05). A positive association between O. viverrini infection in dogs and their owners was found. In addition, cyprinid fish dominantly infected by metacercaria including Henicorhynchus siamensis (27.7%), Cyclocheilichthys repasson (21.9%), Hampala dispar (14.1%), and Barbonymus gonionotus (6.9%). This study provides basic information required for the development of future effective and sustainable strategies to reduces infection rates, mainly by providing health education and encouraging behavioural changes.
