Cocaine use does not affect mean platelet volume.
Article in Interventional medicine & applied science, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Increased mean platelet volume (MPV) is a marker of platelet activation. Platelet activation with cocaine use is not well studied. We wanted to investigate MPV levels in patients with cocaine-associated chest pain (CACP) as a marker of platelet activation. Retrospectively, MPV of 82 consecutive patients with CACP (group 1) with positive urine drug screen (UDS), without acute myocardial infarction (AMI) (group 1A) and with AMI with elevated troponin (group 1B), were included in the study. The control group (group 2) consisted of 89 consecutive patients admitted during the same time period with acute chest pain (ACP) who had negative UDS and negative cardiac markers with a normal cardiac stress test or normal coronary angiogram. Analysis showed no statistically significant difference of MPV between group 1, 8.46 ± 1.06 fL, versus group 2, 8.7 ± 1.07 fL; p = 0.142; and between group 1A, 8.46 ± 1.05 fL, and group 1B, 8.46 ± 1.09 fL; p = 0.983. By multiple linear regression analysis, MPV was not influenced by cocaine abuse (R = 0.269, R (2) = 0.072, adjusted R (2) = -0.009, p = 0.562). MPV is not elevated in patients with cocaine use even when they had AMI. Further studies may be necessary to investigate the role of platelet activation in patients with cocaine use and chest pain.
