No studies have assessed whether activity levels change over time in an acute LBP population, and whether such changes predict recovery.
If the association is nonlinear, then as pollution levels change over time, the number of deaths attributable to air pollution will vary depending on the level of exposure.
This study is the first to prospectively follow an acute LBP population and investigate how activity levels change over time, and whether activity levels predict recovery.
It was, therefore, not unexpected that the level of knockdown might change over time.
Because AKI biomarker levels change over time depending on the timing and severity of injury [ 9], a functional assessment of renal function might enhance biomarker performance.
Conventional wisdom holds that ocean waves and commercial shipping are the main sources of noise in the deep sea, the panel notes, but there are few data on how noise levels have changed over time.
To determine how congener levels have changed over time, we compared the results from the 1971 1982 samples analyzed by Kang et al. (1990) with recent data from two data sets.
Highly specific and selective S1R radioligands are critical to understanding the in vivo role of this receptor and how its levels change over time in these disease states.
We next examined whether cystatin C levels change over time in ALS patients, and if these changes are associated with clinical disease progression.
