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

introductionIt is well known that platelets from diabetic patients can be resistant to clinically used antiplatelet drugs.

methodsTo assess the phenomenon in more detail, 50 adult patients suffering from type 1 diabetes mellitus (T1D) were recruited and their responses to 7 platelet aggregation inducers, as well as to 3 clinically used antiplatelet drugs (acetylsalicylic acid /ASA/, ticagrelor and vorapaxar) and one experimental compound, 4-methylcatechol, were assessed ex vivo. A control group of 50 generally healthy age-matched controls was also included for comparison.

resultsT1D patients exhibited a lower aggregation reaction to 3 inducers but were conversely more resistant to the effect of ASA and vorapaxar than controls. Ticagrelor tended to be less active in T1D as well. On the other hand, 4-methylcatechol was equally or even more potent in T1D than in healthy controls. Plasma glucose levels above 7 mM were associated with lower platelet aggregation responses to four aggregation inducers. In contrast, the effect of 4-methylcatechol, unlike that of ASA, did not appear to be strongly influenced by glycemia. Further subanalyses, excluding hypertensive patients and significantly more frequently administered drugs, did not substantially modify the results.

conclusionConclusively, 4-methylcatechol seems to be a prototypical antiplatelet compound with a strong effect even in diabetic patients.
