Correlation between red blood cell distribution width and deep vein thrombosis in patients with lower limb fractures.

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: This study aimed to investigate the relationship between red blood cell distribution width (RDW) and perioperative lower-extremity deep vein thrombosis (DVT) in patients aged 18-75 years with lower-limb fractures. Material and methods: From February 2021 to February 2023, we included 766 patients aged 18-75 years with lower-limb fractures. Univariate and multivariable analyses were used to investigate the association between RDW and DVT. The discriminatory ability and cohort-specific exploratory cut-off values of RDW were evaluated using receiver operating characteristic (ROC) curves. Results: ROC curve analysis identified cohort-specific exploratory cut-off values of 43.9 fL for RDW standard deviation (RDW-SD) and 13.2% for RDW coefficient of variation (RDW-CV), and RDW-SD showed better discrimination than RDW-CV ( Conclusion: Advanced age, Hb <120 g/L, higher PLT, RDW-SD ≥43.9 fL, and RDW-CV ≥13.2% were independently associated with perioperative DVT in patients aged 18-75 years with lower-limb fractures. RDW-SD showed better discrimination than RDW-CV.
