Risk Factors for Short and Long-Term Mortality in Acute Pulmonary Thromboembolism: A Retrospective Study.
Article in International journal of general 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
Purpose: Platelet-Lymphocyte Ratio (PLR) and Neutrophil-Lymphocyte Ratio (NLR) are the parameters investigated in acute pulmonary thromboembolism (aPTE) mortality. This study aimed to determine the prognostic value of NLR, PLR, and other parameters in aPTE. A retrospective cohort study was conducted in a Research and Training Hospital. Patients and Methods: The study included 346 aPTE cases, and mortality at the first week, first month, and sixth month were determined as endpoints. The medical files of the cases were examined. Age, sex, date of diagnosis, vital status, the last follow-up date, hemogram, lower extremity venous Doppler ultrasonography, and intensive care unit admissions were recorded. Cox regression analysis was performed to identify prognostic factors associated with mortality, and hazard ratio (HR) and a 95% confidence interval (CI) were reported. Results: Median follow-up was 898.5 days. There was no significant difference in terms of sex on mortality. The deceased cases in the 1st month and 6th month were older than the survivors; among them, intensive care unit (ICU) admission rates were higher, and deep venous thrombosis (DVT) was less frequently detected. In the first week, ICU admission rates were higher in deceased cases, and DVT was determined less frequently among them. NLR was higher in all deceased patients, while PLR was elevated in deceased cases in the first and 6th months. ICU admission and DVT status were consistently associated with mortality across all three time points. NLR was identified as a good prognostic factor for the first month of mortality (95% CI: 1.017-1.168 HR: 1.090). PLR and age were poor prognostic factors; PLR was positively associated with 6th-month survival (95% CI: 1.001-1.005 HR: 1.003). Conclusion: NLR is a good prognostic factor, and PLR and age are poor prognostic factors. DVT may help in early diagnosis, which may be associated with lower mortality.
