The phrase "a calendar time" is not commonly used in written English and may sound awkward.
It could be used in contexts discussing specific times or dates related to a calendar, but it is not a standard expression.
Example: "We need to set a calendar time for our meeting next week."
Alternatives: "a scheduled time" or "a specific date".
On a calendar time basis, relative biomass growth curve became steeper at higher latitudes, indicating a shorter growing season, a narrower harvesting window, and a greater biomass yield penalty for early season harvest.
"The work is of particular importance for forensics use in endangered species because the authors show that C14 can be used to determine the age of death or collection of ivory as well as establishing growth rates, so that other data from the teeth can also be put on a calendar time scale".
The survival models presented above rely on a calendar time scale instead of time on study (time since randomization).
A calendar time variable indicating the time of training will be created and the interaction between this variable and the intervention will be assessed to determine if any significant temporal changes took place.
We included an age adjustment (indicator variables for 2-month age strata from 0 to 11 months and 6-month strata from 12 to 59 months) to control for the changing age distribution of the population over time and a calendar time adjustment (six-month time strata) to control for temporal trends.
Note, that this may well introduce a calendar-time-dependent misclassification and hence bias [ 17], but this will be ignored in the following as we are not studying secular trends in incidence.
Across all calendar time periods, a high level of comorbidity was a negative predictor of 1-year and 5-year cancer survival.
More specifically, we require the sample to include all subjects who have advanced to a certain end-point (failure event) within a given calendar time period–and only these cases.
As the ascertainment is population-based, with a negligible magnitude of missing cases during the recruitment period, it is possible to incorporate in the risk model information about all individuals who were born during a certain calendar time interval and who had passed the recruitment window without being ascertained.
Revich and Shaposhnikov (2008) calculated the observed numbers of death during the cold spells and estimated expected numbers from a corresponding calendar time period over 6 years.
Some are based on the number of newly diagnosed cases (incident cases), others are based on survivors at a given calendar time (prevalent cases) [ 6].
