Prevalence, outcomes, and predictors of mortality among adult intensive care unit patients with sepsis at a Tertiary Hospital in Tanzania: A prospective cohort study.
Article in PloS one, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSepsis continues to pose a significant global health challenge, particularly in low- and middle-income countries, which face a disproportionate burden of sepsis and sepsis-related deaths. The estimated prevalence of sepsis and sepsis-related mortality is higher in intensive care units than in hospitals overall. The burden can be higher in tertiary referral centers that receive patients from different regions. This study aimed to determine the prevalence of sepsis, its outcomes, and the factors associated with these outcomes among adult patients admitted to the Intensive Care Unit (ICU) of the Muhimbili National Hospital (MNH) in Tanzania. METHODOLOGY: This prospective cohort study was conducted over a period of six months from May 16 to November 16, 2023, at MNH. A total of 248 patients were admitted during the study period and screened for sepsis on admission or for the development of sepsis during their ICU stay. Sepsis was defined according to the Sepsis-3 criteria as a suspected infection with a Sequential Organ Failure Assessment (SOFA) score ≥2 within 24 h of ICU admission. Proportions were used for descriptive statistics, and modified Poisson regression analysis was used to identify independent predictors of mortality at a 95% confidence interval, with P < 0.05 indicating statistical significance.
resultsThe prevalence of sepsis was 41.5%. The respiratory system was the most common source of infection (32%), and 22.3% of patients had more than one infection site. The ICU mortality rate was 55.3%, with 35% of patients developing systemic complications during their ICU stay. Factors independently associated with mortality included multiple comorbidities (aPR 3.35, 95% confidence interval [CI], 1.20-9.32; p = 0.021) and a higher SOFA score (aPR 7.08, 95% CI 3.48-14.4; p < 0.001). Early initiation of antibiotics was independently associated with improved survival (aPR 0.47, 95% CI 0.27-0.84; p = 0.011).
conclusionThis study revealed a high prevalence of sepsis and sepsis-related mortality in the ICU. A high SOFA score and multiple complications were independent predictors of mortality. Early initiation of antibiotic therapy was an independent predictor of survival. This underscores the importance of early treatment, close monitoring, and aggressive management in patients with predictors of poor outcome.
