Quality of life after intra-arterial therapy for acute ischemic stroke.
Article in Journal of stroke and cerebrovascular diseases : the official journal of National Stroke Association, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Few data exist about health-related quality of life outcomes after intra-arterial therapy (IAT) for acute ischemic stroke (AIS). We assessed stroke-specific quality of life (SS-QOL) in survivors of stroke after IAT. Consecutive patients undergoing IAT for AIS from 2005 to 2010 were retrospectively identified via an institutional database. SS-QOL (using the SS-QOL score) and disability status (modified Rankin Scale [mRS]) were prospectively assessed via mailed questionnaire. We analyzed quality of life (QOL) scores by domain and summary score, with a summary score of 4 or more defined as a good outcome. Analysis of variance (ANOVA) was used to model the effect of final recanalization status, stroke severity, and mRS on total QOL score. ANOVA and Pearson correlations were used to test the association between stroke severity/mRS and QOL/time since stroke, respectively. Of 99 patients with AIS, 61 responded, yielding 11 interim deaths, 7 incomplete surveys, and 43 complete surveys for analysis. Among responding survivors, overall QOL score was 3.9 (standard deviation 0.7); 77% of these reported good QOL. Scores were higher in recanalized patients in 11 of 12 domains but was significant only for mood. Although mRS was associated with stroke severity, QOL was independent of both. Seventy-seven percent of survivors of AIS who received IAT reported good QOL. Furthermore, these data suggest that SS-QOL is an independent outcome from stroke severity and disability status.
