Article in European journal of clinical pharmacology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02086903 (Pharmacodynamic Effect of Loading And Maintenance Doses Of Clopidogrel Versus Half Doses of Ticagrelor In Healthy Subjects), which is not on this map.

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.

Abstract

purposeThe aim of this study was to assess age and gender effects on ticagrelor pharmacokinetics and pharmacodynamics (PK/PD).

methodsForty healthy individuals [18-45 years (young); ≥ 65 years (elderly); ten men, ten women per age group) received 200 mg ticagrelor.

resultsTicagrelor was rapidly absorbed [time to maximum concentration (C(max)) (t(max)) 2.5-3.0 h], and its major active metabolite, AR-C124910XX rapidly formed (t(max) 3.0-3.5 h) in all groups. Ticagrelor exposure was higher in elderly vs. the young [area under the curve from time 0 to infinity (AUC(0-∞)) 52%; C(max) 63% higher] and women vs. men (AUC(0-∞) 37%; C(max) 52% higher). Mean terminal elimination half-life was slightly longer in women vs. men but was unaffected by age. Similar results were observed for AR-C124910XX (elderly vs. young, AUC(0-∞) 48%; C(max) 61% higher), and in women vs. men (AUC(0-∞) 55%; C(max) 56% higher). Across all groups, ticagrelor produced substantial final-extent inhibition of platelet aggregation (IPA): >90% at 4 and 8 h postdose. Individuals with highest ticagrelor exposure (i.e., elderly) had the lowest IPA, indicating an age-related platelet sensitivity effect. In young individuals, platelet sensitivity was greater in men vs. women. Ticagrelor tolerability was not affected by age or gender.

conclusionsSystemic exposures to ticagrelor and AR-C124910XX were higher in elderly vs. young and in women vs. men. Age- and gender-related changes in IPA were apparent, but substantial IPA was achieved in all groups. No adjustment in ticagrelor dose should be considered necessary based on age and gender.
