Cloning, expression, and characterization of a novel Opisthorchis viverrini calcium-binding EF-hand protein.
Article in Parasitology international, 2012. 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
A novel 22.8 kDa of Opisthorchis viverrini (Ov) calcium-binding EF-hand protein (Ov CaBP) was identified and isolated from an immunoscreening of the adult stage Ov cDNA library by using a human cholangiocarcinoma (CCA) serum. This protein was related to other calcium-binding proteins and conserved among the trematodes. Ov CaBP shared 98% amino acid identity to 22.8 kDa of Clonorchis sinensis CaBP and both were classified as a new group of CaBP EF-hand protein by multiple sequence alignment and phylogenetic tree analysis. The open reading frame of Ov CaBP was 585 bp which encoded for 194 amino acids. The N-terminal part is composed of two calcium-binding EF-hand motifs whereas the C-terminal part contains a dynein light chain motif (DLC). In addition, transcription analysis by RT-PCR revealed that it was constitutively transcribed in all stages, including metacercariae, juvenile, and adult. Furthermore, recombinant Ov CaBP protein (rOv CaBP) was expressed as a soluble protein and antibody generated against this rOv CaBP protein was capable of detecting Ov CaBP in the Ov somatic extracts but not in Ov ES products. This anti-rOv CaBP serum was also used to localize Ov CaBP in Ov infected hamster's liver sections which the distribution of Ov CaBP was located in gut epithelium, miracidia in eggs and slightly in parenchyma. Moreover, rOv CaBP protein showed a calcium-binding property in non-denaturing gel mobility shift assay.
