The year of publication for the primary report for African trials ranged from 1990 through to 2005, with the most frequent year of publication being 1999.
Frequent Year 3-secondary progression relapses predicted modestly longer times to onset of the progressive phase while other variables more strongly predicted shorter times based on more frequent relapses (Table 3).
Three model treatments, frequent (35 year), moderate (70 year), and infrequent (1050 year) fire cycles, were applied to the landscape for 500 year.
Although frequent Years 1 and 2 relapses predict shorter times to DSS 6, 8 and 10, a causal relationship between such attacks and faster disease progression cannot and should not be assumed.
Given the predictive effects of frequent Years 1 and 2 relapses for shortened times to disability endpoints, we hypothesized that patients with higher relapse frequency in Years 1 and 2 must not only have increased probabilities of developing a progressive course but also shorter latencies from disease onset to progression.
More frequent Years 1 and 2 relapses were independently related to significantly shorter times to attain DSS 6 8 10 from onset of progressive phase and the same independent predictive effect was observed on time to progress from DSS 3 to higher disability levels.
I've had many 25,000-mile frequent flier years at several points in my career and a few years flying almost double that.
Agricultural productivity and growth in Mali are under threat from erratic rainfall, resulting in more frequent dry years.
Non-crusted dune crests may thus serve as preferential habitats (fertility belts) for perennial plants, providing refugia for shrubs during frequent drought years.
It is concluded that while sufficient AWC was present at CR to sustain most of the perennial shrubs also during frequent drought years, insufficient moisture was retained at ID to sustain most perennials.
Back-to-backs, though less frequent than years past, take their toll, and lockdown defense is about the only thing you can control.
