Body temperature as a predictor of mortality in multiple trauma patients: aprospective single-centre cohort study.
Article in Scientific reports, 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
Trauma is the leading cause of death among working-age people. Individuals who have experienced trauma are more susceptible to developing accidental hypothermia. This condition has been demonstrated to be associated with poor clinical outcomes. The primary objective of this study was to identify the association between body temperature (BT) and mortality in patients with multiple trauma. A secondary objective was to ascertain whether this association remained significant in patients with body temperature < 36 °C. A prospective cohort study was conducted in a level-3-trauma centre in Barcelona, Spain, between August 2022 and February 2024. Data pertaining to demographics, out-of-hospital and in-hospital clinical variables were collected. BT was categorised as follows: <35 °C, 35–35.9 °C, 36–37 °C, and > 37 °C. Univariable and multivariable logistic regression were conducted to assess the association between BT and mortality. A sensitivity analysis was also performed using a dichotomous BT threshold of < 36 °C. The study comprised 334 patients, with an overall mortality rate of 10.4%. Secondary mortality endpoints were: 24-hour mortality in 6 patients (1.8%), 30-day mortality in 23 patients (6.9%), and in-hospital mortality in 25 patients (7.5%). Hypothermia (BT < 35 °C) was observed in 11.7% of patients, resulting in a mortality rate of 23%. Patients with BT < 36 °C constituted 43.4% of the cohort. Univariable logistic regression revealed a significant inverse relationship between BT and mortality (OR 0.51, 95% CI 0.3–0.7; P < 0.001). Following multivariable adjustment, the association remained robust (OR 0.58, 95% CI 0.37–0.91; P = 0.02). A subsequent sensitivity analysis demonstrated that a BT < 36 °C was an independent predictor of mortality (OR 3.29; 95% CI: 1.23–8.77; P = 0.017). BT was identified as an independent and significant predictor of mortality in patients with multiple trauma. For every 1 °C decrease in BT, the odds of mortality increased by 72%. Patients with a BT < 36 °C exhibited a threefold elevated probability of mortality.
