The delays, which make the data available Out-Of-Sequence (OOS), appear when using physically distributed sensors, communication networks and pre-processing algorithms.
BMI was recorded and patients were defined as obese if their BMI was > 30 (data available from 114 out of 149 patients; 10/19 of deceased patients and 104/128 of survivors).
The frequency of E. coli detection (>1 mLN/100 mL) over a year was calculated for each of the 125 wells having data available for at least 10 out of 11 months of the year (no wells were sampled in December 2008), averaging the result if a well was sampled in the same month in 2008 and 2009.
As a concrete example, the SuperMAG website (http://supermag.jhuapl.edu) had a total of 204 magnetometers with data available on Feb 24 2010, out of the nominal 448 listed, with only 29 south of the equator.
To validate the results obtained with the microarray data, we assessed the expression for the six key genes of the subnetwork along with TWIST1 in RNA-Seq data available for 178 out of the same 197 patients of the TCGA microarray data set.
For biochemical response, one of the two secondary outcome measures, incomplete biochemical data (available on 35 out of 57 patients), and the interference of various drugs (e.g., proton pump inhibitors; Mosli et al, 2012) and renal function (Bech et al, 2012) on serum chromogranin A concentrations, makes serial changes less reliable as an objective measure of response.
Drinking frequencies by beverage type were based on data available for 284 out of 288 participants in the 1901 02 cohort and 696 out of 708 participants in the 1930 birth cohort.
The small number of patients in this study, and subsequent limited gene expression data available in 7 out of 12 patients, means that a conclusion about the variation in gene expression, US parameters and histology throughout the joint space is problematic.
Smoking habits were registered and patients were defined as current smokers, ex-smokers i.e. those who have stopped smoking and nonsmokers i.e. those who have never smoked (data available from 136 out of 149 patients).
When spoligotyping data available from 100 out of 104 MTBC isolates identified in the years 1994 2000 were reanalyzed by merging them into the SITVITWEB database, they were attributed with seven previously described spoligotype lineages.
