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
The co-occurrence of type 2 diabetes mellitus (T2DM) and ischemic stroke presents a significant global public health challenge and is associated with adverse clinical outcomes. The relationship between the Systemic Inflammatory Response Index (SIRI) and mortality in patients with T2DM complicated with ischemic stroke remains poorly understood. This study aimed to investigate the relationship between SIRI and mortality in this population, further exploring the potential mediating role of blood glucose levels. We analyzed data from the MIMIC-IV database, selecting patients with T2DM complicated with ischemic stroke. Using multivariable Cox regression, restricted cubic splines(RCS), and Kaplan-Meier analysis, we assessed the association between SIRI and all-cause mortality. We also employed mediation analysis to examine the role of blood glucose in this relationship. The study enrolled a total of 1235 patients. Elevated SIRI levels were significantly associated with increased 28-day (HR: 1.09, 95%CI:1.07-1.12, P < 0.01) and 1-year (HR: 1.08, 95%CI:1.06-1.10, P < 0.01) mortality in this patient group. A nonlinear relationship between SIRI and mortality in this patient population was evident from the RCS analysis(P < 0.01). Subgroup analysis revealed that the effect size and direction remained consistent across different subgroups, indicating the stability of the results.Mediation analysis estimated that blood glucose accounted for approximately 13.72% of the total association between SIRI and 28-day mortality (P < 0.01), but not for 1-year mortality (P = 0.17). These findings demonstrate that elevated SIRI is associated with increased short- and long-term mortality among T2DM complicated with ischemic stroke. Blood glucose plays a mediating role in the relationship between SIRI and 28-day mortality.
