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
backgroundAspirin-clopidogrel dual antiplatelet therapy and a proton-pump inhibitor are used worldwide to prevent thromboembolism and peptic ulceration in patients undergoing neurointervention. We performed VerifyNow assays (Accumetrics, San Diego, CA, USA) to retrospectively examine the relationship between the effectiveness of antiplatelet agents and different proton-pump inhibitor types.
methodsSixty-four patients with unruptured intracranial aneurysm scheduled for neurointervention received aspirin-clopidogrel dual antiplatelet therapy plus the proton-pump inhibitor lansoprazole (n = 34) or esomeprazole (n = 30). A low response to aspirin and clopidogrel was defined in terms of aspirin reaction units > 550 and P2Y12 reaction units ≥ 230, respectively, by VerifyNow assay. The characteristics, response to antiplatelet therapy, and clinical outcomes were compared in patients treated with lansoprazole or esomeprazole.
resultsThe preoperative mean VerifyNow aspirin reaction units and P2Y12 reaction units were 466.0 ± 67.3 and 205.0 ± 67.6, respectively. The mean aspirin reaction unit value was 482.0 ± 64.1 in the lansoprazole group, and 461.5 ± 70.9 in the esomeprazole group (p = 0.77). The mean P2Y12 reaction unit was 220.0 ± 64.4 in the lansoprazole group, and 174.5 ± 65.0 in the esomeprazole group; there was a significant difference in the clopidogrel response of patient treated with lansoprazole or esomeprazole (p = 0.005).
conclusionsOur VerifyNow assay results suggest that when on lansoprazole fewer patients achieved the therapeutic goal and required extra therapy before neurointervention.
