Association Between Charlson Comorbidity Index Items and Outcomes in Patients With Blunt Trauma Using a Nationwide Trauma Registry Database in Japan.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveUnderstanding a patient's medical history and comorbidities before arrival at a hospital can help select the appropriate medical institution for transport and may be related to outcomes by assisting with treatment after arrival at the hospital. This study aimed to clarify the comorbidities associated with blunt trauma outcomes.
methodsUsing the Japan Trauma Data Bank (JTDB), a nationwide large dataset in Japan, we studied 119,929 cases of blunt trauma among patients admitted to JTDB-participating hospitals from January 2019 to December 2022, excluding those with cardiac arrest before hospital arrival. We compared the groups according to the severity of the trauma, age, sex, and each item of the original Charlson Comorbidity Index (CCI) at the time of discharge and then used Cox regression analysis, a multivariate analysis, to explore the relationship between the outcome and each item of the CCI.
resultsThere were significant differences in 10 of the 19 CCI items between the mortality and survival groups. However, Cox regression analysis, including the bootstrap method, was narrowed down to seven items, and the comorbidities that were significantly associated with mortality were leukemia, moderate or severe liver disease, metastatic malignant neoplasm, moderate renal disease, congestive heart failure, collagen disease, and chronic pulmonary disease in that order.
conclusionComorbidities that can affect the prognosis of blunt trauma were identified from the items in the original CCI. It is beneficial for emergency medical personnel to know about pre-existing comorbidities associated with the prognosis of blunt trauma cases when selecting a transport facility before arrival at the hospital, and the condition of trauma cases with pre-existing or dysfunctional major organs, such as the liver, kidneys, heart, and lungs, should not be underestimated.
