1 · What the graph read from it

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.

2 · The registry

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

introductionApproximately 20% of patients with stroke are anemic, and previous studies have identified a U-shaped relationship between hemoglobin levels and all-cause mortality in stroke survivors. However, these studies have not specifically focused on patients with stroke taking antiplatelet agents. This study investigates the impact of anemia and hemoglobin (HGB) on mortality in this population.

methodsThis study included 356 stroke survivors from the National Health and Nutrition Examination Survey 1999-2018 who were taking antiplatelet agents. It analyzed the impact of HGB levels and anemia on all-cause mortality using Cox regression, examined the nonlinear relationship between HGB and mortality through restricted cubic splines (RCS), and illustrated survival over time using Kaplan-Meier survival curves.

resultsRCS analysis revealed no nonlinear relationship between HGB and all-cause mortality (P for overall < 0.01, P for nonlinear = 0.36), with lower HGB levels associated with an increased risk of all-cause mortality. Cox regression analysis showed that HGB was negatively associated with mortality risk across all models (Model 4: hazard ratio = 0.81, 95% confidence intervals 0.73-0.91, P < 0.01). Additionally, anemia significantly increased the risk of mortality in all models (Model 4: hazard ratio = 2.05, 95% confidence intervals 1.43-2.95, P < 0.01). Kaplan-Meier survival curves demonstrated that the survival rate in the anemic group was significantly lower than that of the non-anemic group (P < 0.01).

conclusionIn stroke survivors taking antiplatelet agents, anemia is associated with an increased risk of all-cause mortality, while HGB levels are negatively correlated with mortality risk.
