Critically ill patients with necrotizing soft tissue infections in the Caribbean area: unsupervised analysis of a retrospective cohort (2014-2023) with identification of factors associated with mortality.

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
backgroundScarce epidemiological data are available regarding necrotizing soft tissue infections (NSTIs) in tropical areas. Here we aimed to describe the clinical and biological features, and outcomes, of critically ill patients with NSTIs admitted to an intensive care unit (ICU) in a tropical setting. Furthermore, we analyzed these findings to identify distinct clinical phenotypes and explore their associations with patient outcomes.
methodsThis retrospective observational study included all patients with NSTIs admitted to the ICU of the University Hospital of Guadeloupe between January 2014 and December 2023. Subgroups of patients having similar clinical profiles were identified through unsupervised clustering (factor analysis for mixed data, and hierarchical clustering on principal components). Univariate and multivariate analyses identified factors associated with 90-day mortality.
resultsDuring the study period, 91 NSTI patients were admitted to the ICU. The median Simplified Acute Physiology Score (SAPS) II was 45 [IQR 40-66], and the median time between hospital admission and first surgical debridement was 8 h [IQR 6-10 h]. While in the ICU, 65% of patients were mechanically ventilated, 75% experienced shock, and 34% underwent renal replacement therapy. The 90-day mortality rate was 32%. Unsupervised clustering revealed three clusters-mild NSTI (n = 23, 25%), severe NSTI (n = 49, 54%), and fulminant NSTI (n = 19, 21%)-which were associated with different ICU courses and outcomes. Subcutaneous emphysema and sepsis-associated encephalopathy were key components influencing cluster identification. Multivariate analysis revealed that mortality was associated with SAPS II, subcutaneous emphysema, >8 h between hospital admission and first surgery, and immunocompromised status.
conclusionUnsupervised analysis of critically ill patients with NSTIs in tropical settings revealed three distinct patient clusters that exhibited unique phenotypic characteristics and clinical outcomes. Upon hospital admission, patients with NSTIs should be carefully screened for sepsis-associated encephalopathy, subcutaneous emphysema, and thrombopenia. The present exploratory results must be confirmed in larger multicentric cohorts.
