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

1. In the present study we have investigated the roles of P2Y(1) and P(2T) receptor subtypes in adenosine 5'-diphosphate (ADP)-induced aggregation of human platelets in heparinized platelet rich plasma. 2. The response to ADP can be characterized as the initial rate or the maximum or final extent of aggregation. The response profile is determined by the concentration of ADP used, being transient at lower and sustained at higher concentrations. 3. The P2Y(1) receptor antagonist, adenosine-3'-phosphate-5'-phosphate (A3P5P) competitively antagonized the initial rate of aggregation (pK(B) 5. 47) and transformed the response profile to a slowly developing but sustained response. Both maximum and final extents were also inhibited by A3P5P although not in a competitive manner (Schild slope <1). 4. The P(2T) receptor antagonist, AR-C67085, competitively antagonized the final extent of aggregation (pK(B) 8.54), transforming the response profile to one of rapid, transient aggregation. Its effect on maximum extent (the most widely used index of aggregation) was complex, and further supported the involvement of both receptor subtypes in the aggregation response. 5. ADP-induced aggregation is a complex phenomenon, the nature of which is determined by the relative occupancy of the two receptor subtypes. While P2Y(1) receptor activation causes a rapid and transient aggregation, the extent of sustained aggregation is determined by the level of P(2T) receptor occupancy. Hence, detailed analysis of the aggregation response is essential to correctly define the purinergic pharmacology of the platelet and interpretation of results is critically dependent on the response index chosen.
