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

Background & objectives: : Immune complexes (ICs) play a crucial role which can either be beneficial or pathological to the host. Involvement of circulating immune complexes (CICs) has been shown in tuberculosis (TB) cases (adults and neonates form), but its immunomodulatory effect has not been studied in vivo. Hence, this study was carried out to understand and explore the prognostic therapeutic potential of CICs on the host immune system in guinea pigs animal TB model. Methods: In this study, the guinea pigs (group I) were immunized with in vitro synthesized antigen excess IC (AgX-IC), group II with antibody excess IC (AbX-IC) and group III with phosphate-buffered saline. All these animals were sensitized with Mycobacterium tuberculosis H37Rv before immunization and subsequently infected with M. tuberculosis H37Rv strain post-immunization with IC. Results: Mortality was observed in animals belonging of groups II and III, while all animals in group I survived. A steady increase in the body weight of animals immunized with AgX-IC was observed when compared to the other groups. The infection load in the spleen and lungs was less in animals from group I when compared to the other groups. The CICs were found to be in higher concentration in serum of IC-immunized guinea pigs when compared to ICs non-immunized animals. Interpretation & conclusions: Based on our findings, it can be speculated that the ICs may have a protective immunomodulatory role pertaining to disease progression and development of pathology. As a new perspective, with further insight into the underlying mechanism of action and correlation with clinical data, ICs may also be used as a potential tool for assessing the immune status of the infected individuals, especially the close contacts of TB patients.
