Stability of plasma human immunodeficiency virus load in VACUTAINER PPT plasma preparation tubes during overnight shipment.
Article in Journal of clinical microbiology, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
VACUTAINER PPT plasma preparation tubes were evaluated to determine the effects of various handling and shipping conditions on plasma human immunodeficiency virus (HIV) load determinations. Plasmas obtained from PPT tubes stored and shipped under nine different conditions were compared to conventional EDTA tube plasmas stored at -70 degrees C within 2 h after phlebotomy. Compared to viral loads in frozen EDTA plasma, those in PPT tube plasma that was frozen immediately and either separated or shipped in situ were not significantly different. Viral loads in PPT tube plasma after storage for 6 h at either room temperature or 4 degrees C, followed by shipment at ambient temperature or on wet or dry ice, were not significantly different from baseline viral loads in EDTA or PPT plasma. The results of this study indicate that the HIV load in PPT tube plasma is equivalent to that in standard EDTA plasma. Plasma viral load is not affected by storage or shipment temperature when plasma is collected in PPT tubes. Furthermore, plasmas can be shipped in spun PPT tubes, and the tubes provide a safer and more convenient method for sample collection and transport than regular EDTA tubes.
