Table 3 summarises number of headache spells precipitated by any particular trigger at 3 months' follow up in 186 subjects.
Duration histograms summarise numbers of dives into six bins, with the upper limits at: 2, 5, 10, 15, 25 and >25 min. The lower limit of the first bin was set at 0.5 min. Time-at-depth (TAD) bins summarise the time spent at different depths into 8 bins with upper limits set at 2, 5, 20, 40, 60, 80, 100 and 120 m, because the maximum depths in the study areas were 120 m.
The SDRs provided up to seven partly independent measurements of diving behaviour: Depth histograms summarise number of dives per six hour period into six bins with upper limits at 5, 10, 20, 40, 80, and >80 m.
Counts and percentages were used to summarise number of deaths within 30 days (crude mortality), number of patients treated at two or more hospitals, sex, number of previous admissions (pooled into categories 0, 1, 2, 3 10, and 11 and more) and Charlson index (pooled into categories zero (score=0), mild (score=1, 2), moderate (score=3, 4) and severe (score=5 and above)).
Figure 1 summarises the numbers of registrations by year across the three funding categories.
Figure 3 summarises the numbers and percentages of readmissions assigned to each category, and table 1 gives estimates of the percentage of readmissions in each category subject to mandatory non-payment based on English NHS guidelines.
Table 1 summarises the numbers involved in the study.
Table 1 summarises the numbers of transcribed pseudogene annotations (TPAs) in different categories and data sets.
Table 2 summarises the numbers of participants completing each test and summary measures for these tests.
Table 1 summarises the numbers of examiners in each of the significance categories for the two sets of exams, and the four different indices of examiner behaviour.
