A comparison of the effects of ticagrelor and clopidogrel in patients with acute ST-segment elevation myocardial infarction: a systematic review and meta-analysis of randomized clinical trials.
Synthesis in BMC pharmacology & toxicology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
backgroundRupture of unstable coronary atherosclerotic plaque leads to acute ST-segment elevation myocardial infarction (STEMI). Dual anti-platelet therapy is one of the main treatments, and the combination of Aspirin and Clopidogrel is recognized as the standard oral regimen in most cases. Ticagrelor is a new generation of P2Y12 receptor inhibitors. We aimed to compare the effect of Ticagrelor and Clopidogrel in the treatment of patients post-STEMI.
methodsThis study investigated Pub Med, Scopus, Google Scholar Web of Science, and Embase Cochrane Library clinical trials.gov databases. Heterogeneity between studies was assessed using the I2 index and the Q statistic. The random effects model was used to combine studies and the Funnel plot and Egger's test were used to assess the publication bias.
resultsEleven studies were included in this meta-analysis. 5274 patients in the Ticagrelor and 5,295 patients in the Clopidogrel groups were examined. The mean age of the patients was 58.84 years (2.70) and 59.92 years (3.19) in the Ticagrelor and Clopidogrel groups, respectively. Based on the results of the meta-analysis, compared to Clopidogrel, Ticagrelor had decreased the outcomes of mortality, recurrent myocardial infarction, stroke, and Major Adverse Cardiovascular Events (MACE). However, the post-myocardial infarction bleeding according to Bleeding Academic Research Consortium (BARC) criteria and reperfusion state regarding thrombolysis in myocardial infarction (TIMI) Flow Grading system showed no differences in both groups. However, these effects were not statistically significant.
conclusionsTicagrelor decreased the chance of mortality, re-infarction, stroke, and MACE in post-STEMI patients compared to clopidogrel. But there was no difference in the chance of major bleedings (BARC ≥ 3) and improvement in TIMI grade flow between these two drugs. However, none of these findings were statistically significant, and more studies are needed to reach definitive results.
