Factors influencing mortality in patients with abdominal trauma undergoing damage control therapy.
Observational study in Revista do Colegio Brasileiro de Cirurgioes, 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
objectivesDamage control surgery aims to reduce mortality in patients with severe abdominal trauma by limiting prolonged interventions under unfavorable physiological conditions. This study aimed to identify factors associated with mortality in these patients, including sex, age, cause and mechanism of injury, trauma severity index, hypothermia, metabolic acidosis, and variables related to intensive care, anesthesia, surgical management, and laboratory findings at admission to the intensive care unit (ICU).
methodsThis retrospective observational cohort study analyzed 136 medical records of patients with abdominal trauma who underwent damage control surgery at a tertiary trauma hospital in Curitiba, Paraná, Brazil. Clinical, surgical, and laboratory variables were evaluated. Survivors and non-survivors were compared using univariate and multivariate statistical analyses to determine the significance of the findings.
resultsRelevant findings included higher trauma severity scores among patients who died (mean Injury Severity Score [ISS] of 34 in non-survivors vs 29 in survivors; p=0.017). Hypothermia at admission was significantly associated with mortality. Metabolic acidosis at ICU admission was also associated with unfavorable outcomes, represented by a low bicarbonato value as well as a low base excess (BE) value of -12 compared with -8.6 (p<0.001).
conclusionsHigher ISS values, more negative BE, and hypothermia were independent predictors of mortality in patients undergoing damage control therapy for abdominal trauma.
