Comorbidity characteristics and impact in patients with acute pulmonary thromboembolism: a retrospective study.
Article in BMC pulmonary medicine, 2025. 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
backgroundAcute pulmonary thromboembolism (PTE) is the third leading cause of cardiovascular mortality with increased incidence. Comorbidities are prevalent among PTE patients, yet their characteristics and impacts have not been thoroughly investigated. Thus, this retrospective study aims to explore the comorbidity characteristics and impact in patients with acute PTE, so as to provide a reference for comorbidity management and risk assessment in acute PTE patients.
methodsA retrospective study was conducted on 243 patients with acute PTE in Beijing Hospital between January 2009 and December 2015. Univariate and multivariate Logistic regression analysis were performed to analyze the associations between comorbidity, and risk factors, mortality and adverse events risk.
resultsThe mean age of the 243 acute PTE patients was 67.18 ± 12.96 years, with 123 (50.6%) females. Univariate analysis showed patients aged 65–75 years had 5.37-fold (vs. <45years, p = 0.024), 26.60-fold (vs.<45years, p = 0.005) and 6.00-fold (vs. 45-55years, p = 0.031) risks of having 1,2, and ≥ 3 comorbidities, respectively. Patients aged ≥ 75 years had 17.11-fold (vs. <45years, p = 0.013) and 5.00-fold (vs. 45-55years, p = 0.036) risks of having 2 or ≥ 3 comorbidities. Multivariate analysis showed patients aged 65–75 years had 29.79-fold (vs. <45years, p = 0.008) and 6.31-fold (vs. 45-55years, p = 0.029) risks of having 2 or ≥ 3comorbidities, respectively, and patients aged ≥ 75 years had 17.38-fold (vs. <45years, p = 0.022) risk of having 2 comorbidities. Additionally, univariate analysis showed genitourinary tumors (OR = 4.75, p = 0.017), gastric cancer (OR = 8.96, p = 0.032), and chronic nephritis (OR = 18.00, p = 0.020) were significantly associated with increased mortality risk, and lung infection (OR = 3.07, p = 0.049),chronic obstructive pulmonary disease (OR = 3.63, p = 0.046),and nephrotic syndrome (OR = 14.00, p = 0.033) had higher risks of adverse events. Multivariate analysis showed that genitourinary tumor (OR = 7.86, p = 0.005),gastric cancer (OR = 16.81, p = 0.012), leukemia (OR = 22.00, p = 0.046), and chronic nephritis (OR = 28.62,p = 0.018) significantly increased mortality risk, and liver cirrhosis (OR = 8.99, p = 0.038) and nephrotic syndrome (OR = 26.58, p = 0.021) significantly increased adverse events risk.
conclusionsAge is an independent risk factor for comorbidities burden in acute PTE patients. Genitourinary tumors, gastric cancer, leukemia, and chronic nephritis, significantly increase mortality risk, and liver cirrhosis and nephrotic syndrome are associated with higher adverse events risk. These findings highlight the need for personalized comorbidity management and risk assessment in acute PTE patients, particularly among the elderly.
