RESULTS: Only 41% of respondents were aware of their increased risk for stroke (including less than one half of patients with previous minor stroke).
The control/case ratio in the case control study was 0.7 (48/68), indicating we included less than one control per case.
Taken together the core model reproduces the active NF-κB dynamics of the Kearns model very well, despite the fact that it includes less than one third of the parameters and less than half of the variables of the original Kearns model.
However, the Northern Region study included less than one tenth the number of cases in the present study and variations in rates with respect to diagnostic sub-groups are probably due to the very small numbers resulting in unstable rates for a number of the groups.
Only one-quarter of Americans support turning Medicare into a voucher program, including less than one-third of Republicans.
With the war, less than half the imports are flowing in, including less than one-third of all medicines.
Most studies have included less than 500 cases, though one publication reported a larger sample size of 553 autopsies, including fetuses, stillborn and liveborn infants [ 7].
Sample sizes ranged from 18 to 128 patients, with seven studies including less than 50 patients, and only one study with more than 100 patients.
Only three studies (Herring et al, 1986; Lavey et al, 1990; Fisher and Anderson, 1994), the smallest ones, which included less than 50 SMN cases, estimated a relative risk of above 1.5.
The exact question used was, "In the last 6 months, when you were using, which of the following drugs did you inject and how often?", with possible answers including, "Less than once per month/One to three times per month/About once per week/Two or three times per week/At least daily".
