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

introductionThe benefit of intravenous thrombolysis (IVT) prior to EVT in acute ischaemic stroke (AIS) remains debated. We evaluated the association of the susceptibility vessel sign (SVS) with clinical and angiographic outcomes and assessed whether its presence modified the effect of IVT. PATIENTS AND

methodsWe retrospectively analysed patients with anterior circulation large vessel occlusion from the multicentre ETIS registry who underwent EVT. Susceptibility vessel sign presence and extent were assessed on MRI and categorised as binary (SVS- vs SVS+) and 3-class (SVS-, SVS+, SVS++) variables. Multivariable regression was used to evaluate associations and interactions between SVS and IVT for the primary (90-day mRS 0-2) and secondary (90-day ordinal mRS and mortality, first-pass expanded thrombolysis in cerebral infarction [eTICI] 2c-3 and final eTICI 2b-3) outcomes.

resultsAmong the 1250 patients analysed, 909 were included. Susceptibility vessel sign was present in 84.5% of patients and associated with improved 90-day mRS 0-2: adjusted odds ratio (aOR) 2.03; 95% CI, 1.18-3.46. No interaction between SVS and IVT was observed for clinical outcomes. However, SVS modified the effect of IVT on final TICI 2b-3 (Pinteraction = .03): IVT + EVT was associated with higher odds of successful reperfusion in SVS+ patients (aOR 2.00; 95% CI, 1.28-3.52) but not in SVS- patients (aOR 0.60; 95% CI, 0.16-1.97). In a secondary analysis using 3-class SVS, only SVS++ (larger hyposignal) was significantly associated with better outcomes and showed interaction with IVT for final eTICI 2b-3.

conclusionSusceptibility vessel sign, particularly SVS++, was associated with improved clinical outcomes and enhanced the effect of IVT on reperfusion success in EVT-treated AIS.
