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
backgroundRisk stratification after transcatheter aortic valve implantation (TAVI) remains challenging, particularly in elderly patients with substantial frailty and comorbidity burden. The hemoglobin-to-red cell distribution width ratio (HRR) has recently emerged as an integrated biomarker reflecting anemia, systemic inflammation, and nutritional status. However, evidence regarding its prognostic value in patients undergoing TAVI remains limited.
methodsThis retrospective observational study included 584 consecutive patients who underwent TAVI for severe aortic stenosis between 2019 and 2023. Baseline HRR was calculated from preprocedural laboratory measurements. Patients were categorized into the low HRR group and the high HRR group according to a receiver operating characteristic-derived cut-off value (0.74). The primary endpoint was long-term all-cause mortality. Multivariable Cox regression analyses evaluated HRR as both a continuous and a categorical variable. Additional receiver operating characteristic, reclassification, and restricted cubic spline analyses were performed.
resultsPatients in the low HRR group experienced significantly higher in-hospital, 30-day, one-year, and long-term all-cause mortality compared with those in the high HRR group (all
conclusionsPreprocedural HRR is independently associated with long-term all-cause mortality after TAVI. HRR may provide complementary prognostic information when integrated into multiparametric risk assessment strategies for elderly patients undergoing TAVI.
