Matching criteria included recruitment center, age at enrollment (±6 months), time of day of blood collection (±1 h), follow-up time (as close as possible), time between blood draw and last consumption of food or drinks (<3, 3 6, >6 h).

In addition, worries about a possible time mismatch between assets and liabilities will cause the prudent pension manager to favour domestic bonds over equities, foreign or domestic.
The PF is initialized at time k = 0, and the source is assumed to become active at time instant k < 0. The maximum value of the random variable kstart is a prior and is proportional to the maximal possible time duration between source arise and first detection (cf. (20)).
An additionally important aspect of scenarios is the possible time span between some of them belonging to the same operation (please note that the concept operation is something very abstract and time consuming, such as scenarios like "starting an operation", "waiting for something to happen", "do something", etc).
Latency analyses were used to examine whether there is a possible time lag between choline and betaine intake and risk of breast cancer.
Fine-tuned case-mix adjustment when comparing hospitals before/after, and with/without the policy, taking into account the possible time lag between implementation and results.
Manual transcription is also time-consuming, and in complex cases, the number of parameters that need to be documented may increase greatly; and may create a possible time lag between observation and charting.
Additionally, due to the lack of data concerning the time period between the last experienced AOM and answering the questionnaire, there might be a recall bias arising from a possible time delay between experiencing the acute disease and giving statements from memory.
Another possible reason, which might partly explain the earlier peak in recorded ovarian cancer in the GPRD, could be a possible time lag between recording a diagnosis in GP records and informing the cancer registries (data for which come mostly from other sources including hospitals and the death registry).
We investigated possible time trends, sources of between hospital variation, and potential benefits of targeting between hospital variation for better adherence to guideline recommended treatment to improve survival of patients with acute myocardial infarction.
