For the 367440 SNPs with less than 1% missing percentage from all 22 chromosomes, in total 357 SNPs were selected from this data set.
On the other hand, significantly lower missing percentages were identified in the remaining items with higher values (7.6%) both in item 22 ("Have less control because of poor eyesight") and item 23 ("Rely on others because of poor eyesight").
The column under "Missing" refers to the missing percentages of genotypes in the groups.
Fold changes between 0.5 and 2.0 were considered as not differentially expressed and are represented as the missing percentages to 100% in each tumor entity.
The highest missing values were identified in the questions regarding 'Driving' (missing percentages of 59.0 % and 73.3 % in items 15 and 16, respectively).
The highest missing values were identified in the questions regarding "Driving" (missing percentages of 13.4% and 68.2% in items 15 and 16 respectively).
N.B. – Missing percentage are low in general.
They are both righthanders who don't miss many bats and keep the ball down: according to Fangraphs.com, they ranked 76th and 79th out of 94 qualifying starters in swing-and-miss percentage, but 12th and 30th in ground-ball rate.
Internal validity was analysed by (i) Completion of questions and missing data: percentage completion by respondents in the surveys was calculated; (ii) Internal agreement within questions: levels of expected response combinations (as percentage) were calculated within each set of questions.
The ranges for ordinal variables, and the percentage missing, are given in parentheses.
