The values did not differ substantially per year, and as no relevant differences could have been expected with such a small group, we did no statistical significance tests.
ORs did not differ substantially among SES categories, as indicated by the nonsignificant interaction terms in all analyses (data not shown).
This exclusion was unlikely to introduce selection bias, because it was made on municipality level and the characteristic of the excluded individuals did not differ substantially from the included, as shown in Table 4.
Growth rates in high current concentrations were greater in 6 out of 9 strains where as they did not differ substantially in the remaining 3. It is evident therefore that the low nutrient concentration was growth limiting.
Although just 71.2% of patients tested TST-positive when using the recommended cut-off of ≥5 mm of induration, this did not differ substantially from the proportion defined as positive using a cut-off of ≥10 mm of induration (64.3%) with a difference of just 6.9%.
At the final study visit (12 weeks) the change in mean morning clinic PEF (primary outcome), as compared with baseline, did not differ substantially between the azithromycin and placebo treatment groups (mean difference -10.3 (95% CI 47.1 26.4 L·min−1), p=0.58) (table 1).
Changes in clinical outcomes after atorvastatin treatment are listed in Table 2 and illustrated in Figure 2. At 4 weeks, the change in mean morning PEF, as compared with baseline, did not differ substantially between the atorvastatin and placebo treatment periods [mean difference -10.67 L/min, 95% CI -38.70 to 17.37, p = 0.449].
As the results did not differ substantially between the two specifications, we present the full case analysis below.
