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

The voltage-gated Ca(2+) channel β-subunit is a member of the membrane-associated guanylate kinase family and modulates kinetic properties of the Ca(2+) channels, such as their voltage-dependent activation and inactivation rates. Two cDNA clones were identified to encode each β-subunit isotype of the voltage-gated Ca(2+) channel of Clonorchis sinensis, CsCavβ1 and CsCavβ2, which consist of 606 and 887 amino acids, respectively. CsCavβ1 was found to be similar to the β-subunit containing two conserved serine residues that constitute the consensus protein kinase C phosphorylation site in the β-interaction domain (BID). CsCavβ2 had cysteine and alanine residues instead of the two serine residues conserved in BID and was homologous to variant β-subunit of Schistosoma mansoni and Schistosoma japonicum. CsCavβ1 and CsCavβ2 were almost equally expressed in the adults and metacercariae, but were more expressed in adult C. sinensis than in metacercariae. Collectively, our findings suggest that substitution of the two serine residues in BID of CsCavβ2 may render C. sinensis sensitive to praziquantel.
