Clinical features of pulmonary infarction in older patients with pulmonary embolism: a retrospective comparative study.
Article in Frontiers in 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
Objective: To analyze the clinical characteristics of pulmonary infarction in older patients with pulmonary embolism. Methods: We conducted a single-center retrospective study of 71 patients with pulmonary infarction (PI) secondary to pulmonary embolism (PE) confirmed by CTPA between January 2016 and December 2021. Participants were stratified into older (≥65 years) and non-older (<65 years) groups. We compared baseline characteristics, laboratory/imaging findings, Wells scores, PE severity, diagnosis and treatment using chi-square and Mann-Whitney U tests. Results: PI occurred in 17.1% (71/414) of PE cases, comprising 36 older patients and 35 non-older patients. Significant differences were observed in pleuritic chest pain, hemoptysis, cardiovascular disease, cerebrovascular disease, pulmonary hypertension, and ECG changes between the two groups ( Conclusion: Older PI patients have less typical chest pain, hemoptysis or ECG changes, a high proportion of comorbid cardiovascular/cerebrovascular diseases, and a higher rate of mismatch in the first visiting department. Clinicians should recognize the atypical presentations of PI in older patients and pay increased attention to this population.
