Tumour size were evaluated two times per week by caliper measurements using the following formula: tumour volume=(length × width)/2.
The specimens were evaluated two times by the same observer (kappa-values ranging from 0.75 0.90) and discordant cases were reviewed a third time, followed by a conclusive judgment.
23 The MARVELOUS study did not reveal a statistical improvement so early, which may be related to the lower initial synovitis and bone oedema scores, or due to the fact that the MARVELOUS study simultaneously evaluated six time points, whereas only two time points were evaluated in the Spanish study.
Under the amendments, laboratories like hers must be certified before they can perform tests for the general public, and their performance is evaluated three times a year by the College of American Pathologists.
Corrosion was evaluated four times a year performing visual observations (rust, cracks, delamination) and electrochemical measurements from which corrosion rates were calculated.
Odor intensity (ratings 0 5) and environmental factors, including meteorological condition, PM10, PM2.5, total volatile organic compounds (TVOCs), ammonia and reduced sulfides, were evaluated six times daily.
The residents in the experimental and control groups were evaluated three times: at the beginning of the program (1996), 1 year (1997) and 2 years (1998) later.
A total of 41 nurses were randomly allocated to three groups, which were separately trained, and all were evaluated four times at three-month intervals (before intervention, between each intervention, and after the last intervention).
The blood glucose levels were evaluated three times a week for the appropriate level of blood glucose control and animals were treated accordingly.
The repeated sprint ability was also evaluated three times: during Ex1, during Ex2, and at 24 h during post-exercise period (Fig. 1).
