1 · What the graph read from 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.

2 · The registry

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, a food-borne trematode parasite endemic in the lower Mekong countries, is conventionally diagnosed by stool examination. However, parasitological stool-based diagnosis can be unreliable in light infections. The goal of this study was to develop the immunodiagnosis of opisthorchiasis using cathepsin F cysteine protease of O. viverrini in both indirect and sandwich ELISA assays. A recombinant O. viverrini cathepsin F (rOv-CF) of 40 kDa was expressed in E. coli strain BL21 (DE3), affinity purified, and deployed in ELISA assays. Human sera from 272 cases were investigated by indirect rOv-CF-based ELISA. Positive antibody response to rOv-CF was found in 137 out of 272 cases (50.37 %) using a cutoff OD (0.400) determined by ROC analysis. In comparison to parasitological stool examined for fluke eggs, the gold standard, the rOv-CF indirect ELISA showed a sensitivity and specificity of 62.1 and 84.05 %, respectively. Serum antibody levels correlated well with egg counts per gram feces (EPG) (P < 0.001). In addition, chicken IgY antibody raised against rOv-CF was tested in a sandwich ELISA for detection of coproantigen in the feces of experimentally infected hamsters. The sandwich ELISA using this chicken IgY in combination with rabbit antibody to O. viverrini somatic antigens showed sensitivity and specificity of 93.3 and 78.57 %, respectively. Together, these findings indicated the potential of rOv-CF for diagnosis of opisthorchiasis, including for uses with chicken IgY for detection of coproantigens of O. viverrini.
