Non-typhoidal Salmonella co-infect and complicate Plasmodium falciparum malaria in children under-five: A prospective cohort study on clinical presentation and outcome in Kisantu district hospital, DR Congo.
Observational study in PLoS neglected tropical diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Not yet cited in PubMed.
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.

Abstract
introductionNon-typhoidal Salmonella (NTS) bloodstream infections complicate Plasmodium falciparum (Pf) malaria infections in children under-five, but bacterial co-infections are often missed due to absence of microbiological diagnosis. We compared signs/symptoms and outcome of NTS bloodstream infection, severe Pf malaria and NTS-Pf malaria co-infections.
methodsIn an area with high, stable Pf malaria transmission (Kongo Central, DR Congo), children (>28 days- <5 years) admitted to hospital with severe febrile illness were enrolled during 18 months (NCT04473768/NCT04850677). Data (in-hospital and 1-month post-discharge) were prospectively collected.
resultsNTS bloodstream infections and severe Pf malaria were diagnosed in 12% (331/2682) and 52% (1389/2682) of enrolled children, respectively. NTS-Pf co-infections occurred in 10% (264/2682) of enrolled children, i.e., Pf malaria co-infected 80% (264/330) of NTS bloodstream infections and NTS co-infected 6% (78/1389) of severe Pf malaria. In children with recent Pf malaria (i.e., HRP2-antigen persistence with negative microscopy), NTS occurred in 32% (173/545), making recent malaria a major risk factor for NTS (OR=5.85, p < 0.001). Compared to severe Pf malaria, age under-two (OR=2.19), > 3 days of fever (OR=3.28) and acute malnutrition (OR=2.20-3.48) were risk factors for NTS (p < 0.001) and NTS cases more often had hypoglycemia, grunting, hepato-/splenomegaly, jaundice or altered consciousness, but overall clinical presentation was not discriminative. In-hospital NTS case fatality was high (24% versus 3% in severe Pf malaria), occurred within 2 days of admission in 64% of deaths, and was preceded by general danger/sepsis signs. NTS cases had slower fever resolution, more frequent in-hospital fever recurrence, longer hospital stays, and more post-discharge deaths (n = 4) than severe Pf malaria cases.
conclusionNTS and Pf malaria frequently co-infected children under-five. Severe Pf malaria and NTS bloodstream infections could not be distinguished clinically, but fatality rates were higher in NTS. Low thresholds for empirical NTS antibiotics and early danger sign recognition triggering sepsis care might improve outcome.
