Excluding levels with zero estimates from the analyses did not change the results, so we always kept them in the models.
Aside from the foot and ankle literature, which used methodology similar to ours, the other sub-specialty reviews excluded level V studies, which gave a falsely elevated proportion of level I and II papers.
After women who received BMZ or HYD were excluded, levels of IL-18 in preeclampsia were similar to those of controls (213 ± 87 pg/mL, P =.69).
However, upper confidence intervals could not exclude levels of risk that would be predicted based on data from the study of atomic bomb survivors.
Prophylactic irradiation excluding the Level IV and supraclavicular region does not increase the risk of regional recurrence in N0 disease.
Craigslist also cut off the ability for Google and other search engines to index its listings in its cache, by excluding high-level categories in its robots.txt file.
Thus, the negative results for percent LEP in our preferred model (NL2) are not an artifact of excluding school-level controls for LEP peers.
The 95% confidence limits for all point estimates all excluded zero (level of agreement that would be expected by chance).
If the outliers are excluded, the level of stepping in the trained irradiated at 13.5 cm/s is significantly better (p = 0.04) than that of the non-trained group.
On the other side we excluded patient level indirect costs including productivity changes.
