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

Hyperglycemia at the time of ischemic stroke has been associated with poorer outcomes. Preclinical literature suggests that hyperglycemia is an independent prognostic factor and the vasculature is more vulnerable to reperfusion injury. We applied a method to match subjects on important baseline factors to test whether, independent of stroke severity, stroke subtype influences the effect of hyperglycemia on outcome after recombinant tissue plasminogen activator (rt-PA). We reanalyzed the NINDS rt-PA dataset with respect to matching variables baseline NIHSS, age, and investigator-determined stroke subtypes small-vessel occlusive stroke (SVS), large-vessel occlusive stroke (LVS), and cardioembolic stroke (CES), above and below a glucose threshold of 150 mg/dl. Ninety-day outcomes were compared. Post hoc baseline matching was excellent in most cases. Hyperglycemia was associated with worsened functional outcome mostly in the LVS subtype with increased mortality in the placebo arm (15.3% mortality normoglycemia vs. 30.6% hyperglycemia; p = .046), worse functional outcome in the rt-PA arm (modified Rankin Score (mRS) 0-1; 46.3 vs. 22.0%; p = .034), and no improvement in functional outcome with rt-PA compared to placebo (mRS 0-1; 25% in both groups). Among hyperglycemic subjects, CES subjects showed significant improvement following rt-PA (p = .027). After matching for baseline severity, the influence of hyperglycemia on outcome was primarily in the LVS subtype, especially after rt-PA. This finding is consistent with a deleterious effect of hyperglycemia on ischemia/reperfusion of symptomatic large arteries. If confirmed, the particular vulnerability of the LVS subtype is important in understanding the role of stroke subtype in the mechanism of worsening and potential treatment of hyperglycemic stroke patients.
