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

backgroundIn endemic countries, people remain at risk of contracting both malaria and typhoid concurrently. Though experimental animal models are very reliable for understanding human diseases, the rat model for Plasmodium-Salmonella coinfection remains underresearched.

objectivesThe present study was performed to characterize the rat model of malaria-typhoid coinfection focusing on physical, hematological, and biochemical parameters.

methodsThirty-four Wistar rats were distributed into five groups including normal control, immunosuppressed, Salmonella-infected, Plasmodium-infected, and Salmonella-Plasmodium-coinfected. Physical signs, mobility, and the fecal appearance of animals were observed. Plasmodium load was monitored through microscopic Giemsa-staining thin blood smears. Concurrently, Salmonella load was evaluated after feces culture in Shigella-Salmonella agar medium based on the McFarland turbidity to determine the number of colony-forming units. Hematological and biochemical parameters were assessed using an automatic hematology analyzer and a spectrophotometer, respectively.

resultsAll the infected animals exhibited at least one clinical sign including piloerection, eye depigmentation, or hyperthermia. Coinfected animals showed severe anemia, leukocytosis, and thrombocytosis compared with monoinfected animals. A significant (p < 0.001) drop in total blood proteins and cholesterol levels was observed in infected rats, with a remarkable decrease in Salmonella-Plasmodium-coinfected rats, whereas transaminase levels significantly (p < 0.001) increased in the same coinfected group.

conclusionThis model provides many important features of Salmonella and Plasmodium sequential coinfection and therefore may be used as a tool to better understand, diagnose, and care for human malaria and/or typhoid pathogenesis.
