Current Prevalence of Infection with Opisthorchis viverrini and Intestinal Parasites in Rural Communities in Northeast Thailand Using Stool Examinations and Serological Screening Methods.
Article in The American journal of tropical medicine and hygiene, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Helminthiases are common neglected tropical diseases in Thailand; thus, regular surveillance is necessary for their control. Among these helminthiases, the small liver fluke, Opisthorchis viverrini (O. viverrini), which is endemic in northeast Thailand, has been the focus of national control and eradication campaigns in the country for several decades. However, these helminths still exist and raise concerns regarding public health. Stool samples, blood samples, and demographic data were obtained from 307 participants. Stool examination via the formalin-ethyl acetate concentration technique (FECT) and agar plate culture (APC) was performed, and parasite eggs and larvae were identified microscopically by experienced technicians. Of 307 individuals, 91 (29.6%) were positive for intestinal helminths and protozoans according to FECT and APC testing. Eggs of the O. viverrini species were the most commonly found (16% of participants), followed by Strongyloides stercoralis (14%), hookworms (1%), Taenia spp. (0.7%) and Blastocystis sp. (0.97%). The positive rates of anti-Opisthorchis viverrini IgG antibody, as evaluated via the immunochromatographic test (ICT) and ELISA, were 26.1% and 31.6%, respectively. The differences in positive results between the FECT (O. viverrini egg-positive) and anti-O. viverrini IgG antibody detected via ICT or ELISA were statistically significant (P <0.05). The ICT and ELISA could possibly be used as the screening tools of choice for the diagnosis of human opisthorchiasis to aid in future treatment, prevention, and control measures.
