Evaluation of a set of refolded recombinant antigens for serodiagnosis of human fascioliasis.
Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Diagnosis of fascioliasis with high sensitivity and specificity antigens play a vital role in the management of the disease. Majority of commercial serological tests use F. hepatica native antigens and indicate wide diversities in test accuracy. Nowadays, recombinant antigens have been introduced as diagnostic reagents offer better test standardization. A combination of highly pure recombinant antigens associated with correct folding will leads to improve specificity and sensitivity of ELISA for diagnosis of Fascioliasis. In this article, Fasciola hepatica saposin-like protein 2 (SAP-2), ferritin protein (Ftn-1) and leucine aminopeptidase (LAP) recombinant antigens were considered as tools for the detection of F. hepatica immunoglobulin G antibodies in persons with chronic human fasciolasis. The recombinant antigens were obtained as fusion proteins, expressed in Escherichia coli and purified by immobilized metal affinity chromatography (IMAC). The refolding processes of denatured recombinant proteins were performed using dialysis method in the presence of chemical additives, and reduced/oxidized glutathione (in vitro). The immunoreactivity of the recombinant antigens was assessed individually and in a combination compared with excretory/secretory antigen (E/S) in an enzyme-linked immunosorbent assay (ELISA) test. The experiments were optimized using 213 serum samples from humans, including patients with chronic fascioliasis, patients with other parasitic diseases, and healthy subjects. The results indicated 95% sensitivity and 98% specificity for rtFhSAP-2, 96% sensitivity and 91% specificity for E/S, 80% and 83.3% for rtFhFtn-1, 84% and 88% for FhLAP, and also, 96% and 95% for combination of recombinant antigens, respectively. In conclusion, the results of this investigation showed that rtFhSAP-2 with the highest specificity and acceptable sensitivity has a considerable superiority compared to mentioned antigens and even in combination with these antigens in serodiagnosis of human fascioliasis.
