Dyspnea after a first episode of pulmonary embolism: prevalence, predictors and long-term associations with health-related quality of life.

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
Introduction: The predictors and consequences of dyspnea after pulmonary embolism (PE) are only rarely investigated. The present study aimed to characterize dyspnea and its associated factors in patients with incident PE up to 2 years after hospital discharge. Methods: Data from the German "Lungenembolie Augsburg (LEA)" cohort study were used. Baseline characteristics of adult patients with a first episode of acute PE were collected during hospital stay. Participants completed postal questionnaires 3, 6, 12, and 24 months after their PE. Dyspnea was assessed using the Chronic Respiratory Questionnaire (CRQ) and the Pulmonary Embolism Quality of Life Questionnaire (PEmb-QoL) was used to measure health-related quality of life (HRQOL). Linear mixed models were used to determine the variables associated with dyspnea. Results: Out of 503 patients (55% male, mean age 62.8 ± 14.6 years), 45%-64% of the participants had dyspnea at any time point. No significant change of dyspnea over time was found. Body mass index (estimate -0.04, 95% CI -0.06 to -0.02, Discussion: Dyspnea is a common and persisting complaint after PE. Symptoms of depression and anxiety are strongly related with dyspnea and dyspnea is significantly associated with impaired HRQOL.
