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/AimVenous thromboembolism (VTE), commonly manifesting as deep vein thrombosis (DVT) or pulmonary embolism (PE), ranks as the third most prevalent cardiovascular condition. Red cell distribution width (RDW) and red cell index (RCI)-both derived from complete blood count (CBC) parameters-have been linked to prognosis and mortality in PE. This study aimed to assess the predictive and prognostic value of RDW and RCI in PE patients, and to compare these markers between those with breast or lung cancer and those without malignancy.Material and methodsA total of 133 patients diagnosed with PE between 2020 and 2023 were retrospectively analyzed. Among them, 81 had no malignancy, 33 had concurrent lung cancer, and 19 had breast cancer. RDW and RCI values were obtained from initial complete blood counts. RCI was calculated using hemoglobin, red blood cell, lymphocyte, and platelet counts. Kruskal-Wallis and Mann-Whitney U tests were used for statistical analysis.ResultsRDW values were significantly higher in patients with lung or breast cancer compared to those without malignancy (p < 0.001 for both). No statistically significant differences were found in RCI values among the groups (p = 0.073). Additionally, no significant differences in RDW or RCI were observed according to mortality status within any group.ConclusionRDW was found to be significantly elevated in malignancy-associated PE and may serve as a useful predictive marker. However, the prognostic utility of RDW and RCI in relation to mortality was limited in all groups.
