Mapping of the country-wide prevalence of non-malarial febrile illnesses in areas with varying malaria transmission intensities in Mainland Tanzania.
Article in Gates open research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Despite the declining malaria burden in endemic countries, reports of febrile episodes do not align with the current patterns of malaria transmission. This highlights the presence of non-malarial febrile illnesses (NMFIs), which are difficult to distinguish from malaria. This study assessed the country-wide prevalence of NMFIs and their patterns across various malaria transmission settings in Mainland Tanzania. Methods: A cross-sectional study recruited patients aged ≥ 6 months from 86 health facilities in all 26 regions of Tanzania. All patients were tested for malaria using rapid diagnostic tests (RDTs). For this study, patients with fever who tested negative by RDT were operationally classified as having NMFIs and their prevalence was determined accordingly, Logistic regression was used to determine factors associated with NMFIs. Results: Of the 18,568 patients tested, 8,273 (44.6%) were considered to have NMFIs because they tested negative by RDT. Higher prevalence of NMFIs occurred in females (45.8%) than in males (42.8%), adults (aged ≥ 15 years, with 50.6%) compared to under-fives (42.6%) and school children (aged 5 -< 15 years, 34.3%), and in very low (65.5%) compared to high transmission areas (34.5%). NMFIs were significantly more likely in females than in males (aOR = 1.18, 95% CI = 1.10-1.26), under-fives (aOR = 1.60, 95% CI = 1.47-1.76) and less likely in high transmission areas (aOR = 0.11, 95% CI = 0.08-0.13), and school children (aOR = 0.70, 95% CI = 0.64-0.77). Conclusion: The findings show a high prevalence of NMFIs overall, and higher prevalence and odds of NMFIs in females and individuals from low and very low transmission areas. These groups should be targeted with appropriate point-of-care tests and treatment strategies.
