This difference is attenuated over time to some extent by a positive effect on rate of change (Table 2).
In particular, we varied the link function in the generalised linear model, the extent to which the linear drift is attenuated over time, the number of knots in the splines used for the age, period and cohort effects in the model and the method used for estimating rates before 1975.
Arien et al. [12], [13] found HIV-1 replication capacity was greater in early (1986 1989) than in recent isolates (2002 2003) from Belgium (n = 24), and suggested that HIV may be attenuating over time.
We have previously hypothesised (Wolin et al, 2007) that the association between physical activity and colon cancer may be attenuating over time as screening decreases the number of colon tumours overall and distal colon tumours in particular.
The experimental results show that signals generated by the coal during gas adsorption are attenuated over time.
Very low calorie programs like Health Management Resources, Medifast, and OPTIFAST resulted in a 4.0% greater short-term weight loss but these losses were attenuated over time.
Also, sequence bias may have occurred, as the ability of veins to dilate may have been attenuated over time or with repetitive maneuvers.
In this study, glycemic control also improved in the SMBG group, but this effect was attenuated over time.
Older people scored differentially worse on IADL compared with PSMS (F1,143.0 = 4.82, p =.030) with a trend for this to be attenuated over time (F3,56.4 = 2.63, p =.059).
Similarly, while the association with prevalence of overweight was attenuated over time, the association was not modified when the growing lags between exposure and effect for prevalences of obesity and smoking habit were taken into account.
This can be explained by the probable faster consolidation of the fracture in Group A, resulting in better function and pain scores in the first weeks, an effect that probably tends to be attenuated over time.
