Association between the prognosis and comorbidity of active cancer in chronic thromboembolic pulmonary hypertension.
Article in BMC pulmonary medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundPrognosis of chronic thromboembolic pulmonary hypertension (CTEPH) has improved after the availability of balloon pulmonary angioplasty (BPA) and approved drugs. However, the clinical effects of cancer, which is one of the associated medical conditions of CTEPH, remain unclear. We aimed to investigate prognosis in patients with CTEPH and comorbid cancer.
methodsBetween January 2011 and December 2022, data of 264 consecutive patients with CTEPH who were treated with pulmonary endarterectomy, BPA, or medical therapy were retrospectively analyzed. The patients were allocated, based on the comorbidity of cancer as of December 2022, into the cancer (n = 47) and non-cancer (n = 217) groups. In the cancer group, active and non-active cancers were identified in 30 (64%) and 17 (36%) patients, respectively.
resultsThe baseline characteristics, hemodynamics, and treatments were similar between the groups. More than half of the cancer were diagnosed within two years before or after CTEPH diagnosis. Twenty-seven patients died during the study period. Among them, 13 (48%) and 7 (26%) died of cancer and right heart failure, respectively. The 5-year survival rate was lower in the cancer group than in the non-cancer group (67.8% vs. 94.5%, p < 0.001). In the active cancer group, the 5-year survival rate was also lower than that in the non-active cancer and non-cancer groups (52.0% vs. 99.5%, p < 0.001 and 52.0% vs. 92.3%, p < 0.001, respectively). Multivariate Cox hazard analysis revealed that hemodialysis (p < 0.001) and cancer (p < 0.001) were independently associated with poor survival.
conclusionPatients with CTEPH rarely die of right heart failure, even if hemodynamically severe at diagnosis in the modern management era. However, patients with CTEPH frequently have comorbid cancer, which may be a strong prognostic factor.
