Regulated upon activation, normal T cells expressed and secreted (CCL5) in platelet concentrate: Role of mode of preparation and duration of storage.
Article in Asian journal of transfusion science. 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
BACKGROUND AND
objectivesPlatelet concentrates (PCs) can be prepared in several different ways, and they can be stored over few days before the use. Regulated on activation, normal T cells expressed and secreted (RANTES) levels in these concentrates may vary depending on the type of preparation and duration of storage of this component. We measured RANTES levels in platelet supernatants in different preparations and with different storage duration. MATERIALS AND
methodsFifteen PCs were prepared by platelet-rich plasma (PRP) and buffy coat (BC) method each. Forty-two single donor platelets (SDPs) were prepared using cell separators Cobe Spectra, Trima Accel, and Amicus. Filtered PCs were prepared using labside and bedside filters. The supernatants were collected after 1, 18, 65, and 112 h of preparation. SDP samples were taken on the 0 day, 3
resultsRANTES at 1 h was 1210 ± 560 pg/ml in PRP-PC, 1384 ± 463 pg/ml in BC-PC. At 112 h, 1617 ± 451 pg/ml and 1949 ± 134 pg/ml, respectively. In SDP, 0-day level was 1850 ± 278 pg/ml and >2000 pg/ml on 5
conclusionThe concentration of RANTES increased continuously from 1 h to 5 days of storage in all PCs. After 65 h, BC-PC showed higher levels of RANTES compared to PRP-PC. Filtered PRP-PCs appear to be the best in terms of low RANTES to prevent allergic reactions and cultures negative.
