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
Background: In this study, we aimed to investigate the prognostic value of the tricuspid annular systolic excursion/pulmonary arterial systolic pressure (TAPSE/PASP) ratio as a marker of right ventricle-pulmonary artery uncoupling in patients listed for lung transplantation. Methods: Between January 2011 and December 2020, a total of 173 patients (114 males, 59 females; mean age: 53.1±12.5 years; range, 18 to 77 years) who had advanced lung disease or pulmonary vascular disease and were included in the lung transplant list were retrospectively analyzed. Demographic characteristics, laboratory values, long-term mortality data, and clinical and cardiac catheterization data of the patients were compared using a TAPSE/PASP cut-off value of 0.55 mm/mmHg. The univariate and multivariate regression analyses were performed to identify the value of TAPSE/PASP ratio in predicting long-term mortality. The maximal selective rank test was carried out to determine the optimal cut-off value for TAPSE/PASP ratio. Results: The univariate regression analysis revealed that the TAPSE/PASP ratio, six-minute walk distance, and albumin level were found to be predictors of mortality (hazard ratio [HR]=0.61, 95% confidence interval [CI]: 0.46-0.80, p=0.007; HR=0.72, 95% CI: 0.56-0.91, p=0.007; and HR=0.77, 95% CI: 0.59-0.99, p=0.04, respectively). In the multivariate regression analysis, the TAPSE/PASP ratio, body mass index, and six-minute walk distance were the predictors of mortality (HR=0.49, 95% CI: 0.34-0.70, p=0.004; HR=0.71, 95% CI: 0.51-0.97, p=0.03; and HR=0.71, 95% CI: 0.54-0.94, p=0.01, respectively).Through the maximal selective rank test, the optimal threshold value for TAPSE/PASP ratio was found to be 0.29 mm/mmHg. Patients with TAPSE/PASP >0.29 mm/ mmHg had an average life expectancy of 47.8 months, while the patients with TAPSE/PASP <0.29 mm/mmHg had an average life expectancy of 17.2 months. Conclusion: Our study results suggest that a TAPSE/PASP ratio of <0.29 mm/mmHg is a poor prognostic factor for long-term mortality in patients on the waiting list for lung transplantation.
