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

Cystic Echinococcosis/Hydatidosis considered as one of the most important parasitic diseases in humans and animals across the world. The goal of the present study was to determine a native antigen with an acceptable sensitivity and specificity to be used in the human hydatid cyst diagnostic methods. In the present study, recombinant P29 antigen was used to detect the antibodies in the serum of patients with hydatid cysts of the liver. In fact, purified recombinant P29 protein is used as an antigen in ELISA. In order to evaluate the recombinant P29 protein for diagnostic ELISA, 25 serums obtained from people harboring the hydatid cysts were tested. The result of the gene expression on a 12% SDS-PAGE gel showed a band with a length of 28 KD. Also, 28KDa band was observed through the reaction of recombinant P29 protein with Anti T7-tag monoclonal antibody in the western blotting method. This protein showed satisfactory results in detecting the hydatid cyst antibodies in the serum of patients having hydatid cysts. Twenty two of 25 hydatidosis serums positively reacted in ELISA using with P29 protein, indicating in 92% of ELISA sensitivity, 95% of specificity, 95.83% of positive predictive value, and 90.42% of negative predictive value for recombinant P29 protein. Whereas the produced recombinant protein P29 showed promising results in the diagnosis of hydatidosis but of more research needs to be done to reach a more accurate conclusion.
