Therefore although the study was relatively limited, it had the purpose to answer a valid query from an archivist and the more extensive data collection also revealed an interesting longitudinal study of newsprint yellowing measurements in archival material for a period over a longer time span than the IBP (whilst borrowing sampling methodology from it).
Brown's remarks also puts him at odds with the Obama administration which, as a condition for states to compete for a series of government grants, including the administration's signature Race to the Top competition, has relentlessly pushed states to develop even more extensive data collection efforts.

Given the importance of maintaining adequate nutritional status in patients undergoing peritoneal dialysis, this trial would have benefited from more extensive data collection on calorie and protein intake.

Having started off as quite simple datasets that included some baseline demographic information, implant types, and outcomes in terms of revisions, registries are now moving towards more extensive data collection.
Table S1 in Additional file 2 shows selected descriptive characteristics of the study population over each of the five youth DISC clinic visits with more extensive data collection; Table S2 in Additional file 2 shows the high correlations between BMI measured at the various study time points; Table S3 in Additional file 2 shows correlations between BMI at each visit with breast density measures.
A more extensive data set will be needed to properly test such division.
Firstly we show that the foetal cardiac signals (ECG) are detectable as separate entity from the maternal ECG (ie. Time incoherence), then we show the advantage of combining ECG and PCG for pregnancy detection with an extensive data collection (more than 2000 cows including a variety of breeds spread over 13 testing farms).
This was a survey embedded in a large population-based prospective cohort with an extensive data collection.
