The phrase "average time of sampling" is correct and usable in written English.
It can be used in contexts related to data collection, research, or experiments where timing is a factor.
Example: "The average time of sampling for this study was calculated to ensure consistency in data collection."
Alternatives: "mean sampling duration" or "typical sampling time".
Cases were recruited from three different study sites in the same region whereas controls were recruited from one of the sites, and we have examined differences in the average time of sampling from the last meal at the different study centres which in principle could affect some analytes influenced by diet/metabolism e.g. insulin, blood glucose, leptin.
Indeed, using these newly developed assays, we found that T1D patients examined several years following MI (average time of sampling, 4.5 years after a MI) showed persistent titers of cardiac autoantibodies in 15 of 18 (83 %) of cases [ 12].
Paired stable and exacerbation sputum was available in 55 subjects (men, n = 43; mean FEV1%% predicted, 51%) with an average time of sampling between stable and exacerbation of 49 days.
Now, we examine the average time of sample collection.
Table 3 reports the average time of a specialization's iteration (sample selection and detector training) on an Intel(R) Core(TM) i7- 3630QM 2.4G CPU machine on each tested dataset with a designed number and size of images.
Consistency of the classifier to reproduce the same classification was tested in 43 patient samples retaken after an average time of 0.8 ± 0.2 years from the initial sampling.
Statistical models indicated that at any time of sampling on average only 47% of all parasite clones present in a host were detected by genotyping [23].
Potential sources of heterogeneity investigated were: year of publication, type of sample, average time from sample collection to cancer diagnoses and study location.
The average time from blood sampling to intravenous injection of 18F-FDG-labeled RBC suspension was approximately 125 min.
In our study, all MAP-shedders identified directly by PCR showed symptoms of paratuberculosis either at the time of sampling or during an average time period of 7 months after sampling.
Another 14 animals from 9 herds (7 animals from 3 suckling cow herds; 7 animals from 6 dairy herds) developed symptoms indicative of paratuberculosis (weight loss, reduced milk yield, intermittent diarrhea) without symptoms of general disease during an average time period of 7 months after sampling (minimum: 1 month, maximum: 16 months).
