Effects of Coincubation With Crystalloids or Medications on Canine Packed Red Blood Cells: An In Vitro Evaluation.
Article in Journal of veterinary emergency and critical care (San Antonio, Tex. : 2001). The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo investigate the effects of coincubation of various solutions and medications with canine packed red blood cells (pRBCs).
designProspective in vitro study. EXPERIMENTAL UNITS: Ten commercially prepared bags of canine pRBCs and fresh frozen plasma (FFP).
interventionspRBCs were coincubated with normal saline solution (NSS), 5% dextrose (D5W), Normosol-R, fentanyl, propofol, norepinephrine, dopamine, or same-donor FFP, as a control. Two pRBC storage times (<7 and 28-35 days) and two incubation times (3 and 30 min) were used. MEASUREMENTS AND MAIN
resultsCBC, light microscopy, methemoglobin assay, and osmotic fragility (OF) testing were performed to assess for hemolysis (decreased RBC count, decreased cellular hemoglobin), RBC swelling (increased mean cell volume [MCV], increased OF), and oxidant injury (increased methemoglobin, Heinz body formation). Results were analyzed by mixed-effect ANOVA to detect significant (p < 0.05) differences; results were also compared with the coefficient of variation of each test method to detect differences exceeding analytical imprecision. All results were compared with coincubation with same-donor FFP under the same conditions (storage and incubation times). NSS caused significant increases in MCV under all conditions. For >28-day-old blood, MCV was significantly increased with dextrose, norepinephrine, dopamine, and fentanyl. OF was mildly but significantly increased with SAL, norepinephrine, dopamine, and fentanyl. Coincubation with propofol resulted in many changes consistent with lipid emulsion artifact, impeding the detection of true additive effects.
conclusionsUnder the most ideal conditions tested (short coincubation of <7-day-old pRBCs), most additives had minimal deleterious effects on RBCs. However, NSS caused mild RBC swelling under all conditions. Mild RBC swelling and increased OF were also observed with most additives in older blood. The propofol lipid emulsion causes analytical interference that confounded the interpretation of results. Further investigation into the safety and efficacy of coadministration of RBCs with other products, including NSS, is indicated.
