To this end, we checked the following clinical parameters: age, MS stage (CIS or Definite), gender, annual relapse rate, EDSS at time of blood sampling, disease duration, age at onset, EDSS change in the last relapse.
In addition, a separate analysis was also made for individuals with more than median (8 years) duration between blood sampling and diagnosis of end-stage renal disease, taking into consideration the other metal (Ery-Hg, and Ery-Pb, respectively), BMI, and blood pressure; the OR for one μg/L increase in Ery-Pb was 1.012 955% CI 1.001-1.022), and for Ery-Hg 0.90 (95% CI 0.76-1.06).
The mean, median, standardised deviation, and range of duration between the time points of performing the HADS and blood sampling of all subjects were 3.6, 2.0, 5.0, and 0 33 days, respectively.
We timed the duration of blood sampling precisely, starting from moment that the birds were caught in the noose carpet (av. duration = 2.10 ± SD: 0.55 min).
It would be interesting to extend the duration of blood sampling following kisspeptin and GnRH infusions beyond 4 h, in order to accurately compare the levels of sex steroid secretion in subjects.
The duration of restraint (including blood sampling) varied among six groups of 12 broilers each (i.e. one bird from one group per pen and handling manner): Group 30 s (30 seconds), Group 60 s (60 seconds), Group 90 s (90 seconds), Group 120 s (120 seconds), Group 150 s (150 seconds) and Group 180 s (180 seconds).
A distally sited cannula was inserted into the contralateral arm for blood sampling and was heated for the duration of the study to achieve arterialization of venous blood.
In the present study, the durations of all subjects between the time points of performing the HADS and blood sampling had a mean value of 3.6 days and standardised deviation of 5.0 days, and those of 95% of all subjects were under 15 days.
The first was about 1.5 hours in duration and included blood sampling, a social questionnaire, and an evaluation of walking speed.
The median duration of disease at the time of blood sampling was 8 years (range 0 66).
