The brainstorm was done by the research team (JD, CvdV, LWTS) based on their experience and data from the preceding study [ 5].
Sleep quality and daytime sleepiness was extracted from the preceding study and categorized in three groups: 1) PSQI ≤ 5 (good SQ) & ESS ≥ 6 (DS); 2) PSQI > 5 (poor SQ) & ESS < 6 (no DS); 3) PSQI > 5 (poor SQ)& ESS ≥ 6 (DS).
The inclusion criteria were: (1) RTx took place at one of the three participating Swiss transplant centers, (2) a functioning renal graft at least 6 months post-Tx, (3) the ability to understand and read German, (4) 18 years of age or older, and (5) participation in the preceding study with poor SQ (PSQI >5 [ 23]) and/or DS (ESS > 6 for increased DS [ 24]) scores.
Figure 2 shows data of storage and loss modulus against frequency for annealed SEBS20 at three different temperatures, viz., 25, 85, and 100°C as measured in the preceding study [ 5].
The same contaminant and nutrient levels as those from the preceding study were analyzed from cord blood samples.
Subjects were instructed to respond, as quickly and accurately as possible, with one button of the keypad when the object depicted had been presented in the preceding study phase, and with another button when it was being viewed for the first time.
To validate its effectiveness, simulations were carried out in the preceding study along with performance evaluations [9].
A review of the preceding studies and the QUANTEC report [ 2] has highlighted several key points which have influenced the design of the RAPRASI study protocol: – Kidneys have a late response to radiation (between 3 and 18 months).
For the first step, to assess the suitability of the Japanese data for the preceding studies [ 7- 9] and examine the dimensionality of the survey, a series of confirmatory factor analyses (CFA) were carried out.
