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

objectiveWe compared the effect of clopidogrel plus aspirin vs aspirin alone on functional outcome and quality of life in the Clopidogrel in High-risk Patients with Acute Non-disabling Cerebrovascular Events (CHANCE) trial of aspirin-clopidogrel vs aspirin alone after acute minor stroke or TIA.

methodsParticipants were assessed at 90 days for functional outcome using the modified Rankin Scale (mRS) and quality of life using the EuroQol-5 Dimension (EQ-5D). Poor functional outcome was defined as mRS score of 2-6 at 90 days and poor quality of life as EQ-5D index score of 0.5 or less.

resultsPoor functional outcome occurred in 254 patients (9.9%) in the clopidogrel-aspirin group, as compared with 299 (11.6%) in the aspirin group (p = 0.046). Poor quality of life occurred in 142 (5.5%) in the clopidogrel-aspirin group and in 175 (6.8%) in the aspirin group (p = 0.06). Disabling stroke at 90 days occurred in 166 (6.5%) in the clopidogrel-aspirin group and in 219 (8.5%) in the aspirin group (p = 0.01). In stratified analysis by subsequent stroke, there was no difference in 90-day functional outcome and quality of life between the 2 groups.

conclusionsIn patients with minor stroke or TIA, the combination of clopidogrel and aspirin appears to be superior to aspirin alone in improving the 90-day functional outcome, and this is consistent with a reduction in the rate of disabling stroke in the dual antiplatelet arm. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that for patients with acute minor stroke or TIA, clopidogrel plus aspirin compared to aspirin alone improves 90-day functional outcome (absolute reduction of poor outcome 1.70%, 95% confidence interval 0.03%-3.42%).
