The phrase "absence length" is correct and usable in written English.
It can be used in contexts where you are discussing the duration of time something is absent or missing.
Example: "The absence length of the equipment was noted in the report, indicating it was out of service for two weeks."
Alternatives: "duration of absence" or "length of absence".
A longer absence length was associated with increased discrepancies between workplace-registered and self-reported sick leave.
Responders and non-responders had a mean workplace registered annual absence length of 2.5 (SD: 5.0) weeks and 4.2 (SD: 8.0) weeks, respectively (results not shown).
Finally, relatively high sensitivities were found in studies where data on absence length, frequency and prevalence of absence were provided as pre-specified categorical questionnaire options [ 5, 17].
Studies providing self-reported data on total absence length, frequency and prevalence as pre-specified categorical options reported relatively high sensitivities (range 79-91% with workplace registers as reference standard) [ 5, 13, 17].
The Whitehall II study and a Swedish replication of Whitehall II found a worse recollection the longer the absence length [ 8, 13] which indicates that valid self-reporting may be limited to absence of short duration.
We expect those with increased absence lengths to recall with less precision compared to those with shorter lengths.
In our study population the ability to recall absence lengths accurately was found in 662 cases (28.7%).
In two papers, the optimum recall period was recommended to be no longer than 2 3 months to obtain valid measures of absence lengths [ 6, 10].
Our data revealed the virtual absence of length restrictions for vector backbone (up to 13.5 kbp) and insert (90 bp to 1.6 kbp).
The absence of length or height facilitates the application of the model since the accurate measurement of tree height in the field can be time consuming for a large number of standing trees.
In absence of length modification, direct sequencing of all putative mutated exons must be done to search point mutations.
