If only one argument is given, it is interpreted as one beyond the last value for a range that starts at 0. Note that an underscore is just another name in the environment as far as the interpreter is concerned, but has a conventional meaning among programmers that indicates the name will not appear in any expressions.
Interestingly, this last value for MFR in patients was slightly but not significantly lower than that in control subjects, due to a significantly lower range of MFR in patients than in control subjects.
Because some participants missed questionnaires towards the end of the study, the last value for ODI score was carried forward, provided that it was within 1 week of study completion.
For LDL-cholesterol and HbA1c, we withheld the last value of each year for longitudinal analysis.
Instead we have "flexibility", which seems, at worst, to mean a £2.60-per-hour and 12-week apprenticeship, and "tailoring", which means imparting skills for the immediate job in hand and of no necessary lasting value for the future.
These results suggest that despite morphological constraints and subjective factors in the delineation of eroded phases, these soils should be viewed as unique pedological entities that hold lasting value for understanding the effects of accelerated erosion on soil morphology, crop production, and ecosystem services.
Over the course of a couple of conversations with Rob, I was particularly interested in how Catalant had positioned itself, its unique features, and how it created lasting value for clients.
To increase the sample size, we interpolated between data points and/or carried forward the last value of an observation for selected variables.
For LDL-cholesterol and HbA1c, we take the last value of each year, but for creatinine e.g. we take the average value of the last two measurements of each year in order to account for the important within subject variability of this variable [ 14].
