Based on the NELSON trial, volume doubling time assessment is also recommended for intermediate size nodules (Horeweg et al., 2014).
Preoperative planning for the location and quantity of hydroxyapatite to be used was determined by a trial volume injection using local anesthetic.
Since single trial volumes cannot be increased indefinitely, it becomes necessary to combine trials for further gains in statistical power.
Experimental protocols present differences among the trials, concerning volume of autologous blood collected, speed and time of centrifugation, method of administration, activating agent, presence of leukocytes, final volume of PRP, and final concentration of platelets and growth factors.
In summary, in all trials the volume of blood taken for diagnostic testing between the blood conservation devices and control groups was significantly less; however, only in the larger trials did this result in a reduced rate of fall in Hb.
During trials, the volume was then adjusted depending on distance to the mob.
When LBNP was applied during the AMB trials, stroke volume immediately decreased.
Nearly 100% power was achieved for all three test concentrations with 7 trials (total volume = 49 m).
At prescriber level, doctors' interest in particular therapeutic areas, participation in clinical trials, and volume of prescribing either in total or within the therapeutic class of the new drug increase the likelihood of early adoption.
Some authors have pointed out that the VISEP 7 and 6S 6 trials, investigating volume resuscitation in a critical care setting, recruited patients up to 24 hours after diagnosis of sepsis or septic shock, therefore suffering from protocols not reflecting clinical reality.
