The phrase "attrition data collection" is correct and usable in written English.
It can be used in contexts related to research, analysis, or business where data regarding attrition rates or loss of participants is being gathered.
Example: "The study focused on attrition data collection to understand the factors leading to participant drop-out rates."
Alternatives: "data gathering on attrition" or "collection of attrition statistics".
We had significant attrition after the data collection point at six months and in retrospect we had not factored in the short disease trajectories of some patients or that some patients may have different notions of time.
In other words, attrition between points of data collection does not appear to be a confounding factor.
Overall attrition rates for anthropometry data collection was 3.1% (250) at six months and 6.2% (242) at 12 months.
We intended to assess the methodological quality of the study designs and describe each included study against the following criteria: allocation to intervention/control; confounders; blinding; data collection methods; attrition; fidelity; and follow up.
Figure 1 shows the flowchart of ineligible/excluded men, completeness of data collection and attrition from the study between recruitment and 12 months post-treatment.
To minimise attrition, prior to follow-up data collection, services will receive letters thanking them for their participation to date and reminding them that they will be telephoned again to participate in follow-up data collection.
To minimise attrition, prior to follow-up data collection, all participating services in intervention groups will receive letters thanking them for their participation to date and reminding them of the follow-up data collection.
While the within-group change in SF-12 MCS in our controlled trial was comparable with that observed in the previous study (3.5 vs 3.8), this should be interpreted cautiously due to substantive methodological differences in data collection and attrition.
287 Trial investigators must often seek a balance between achieving a sufficiently long follow-up for clinically relevant outcome measurement, 122 288 and a sufficiently short follow-up to decrease attrition and maximise completeness of data collection.
It is predicted there will be a 5% attrition rate during the 12 month data collection time period.
