On top of all this, the sample sizes of these retrospectively selected subgroups were not big enough for truly meaningful conclusions to be drawn.
Until now, the prognostic value of microcirculatory alterations in critically ill patients has been mainly evaluated in highly selected subgroups.
They are used to determine the magnitude and impact of diseases or other conditions in populations or in selected subgroups of populations.
However, it is likely that alternative modalities of communication may be preferred by and will be more effective in selected subgroups of subjects, representing a new and interesting field of headache research and care.
However, it is highly likely that imaging will only confer additional information in selected subgroups of subjects in combination with traditional risk factors and (novel) serological markers.
Figure 1C shows the aOR and 95% CI for selected subgroups.
Special attention will be paid to acute smoking and corticosteroid insensitivity in selected subgroups.
In view of our findings, we then consider the determinative confounding factor in the selected subgroups.
It is then possible to derive population statistics for the entire population or for selected subgroups.
Figure 1A shows the aOR and 95% CI for selected subgroups.
In selected subgroups the relevance of the adequacy of empirical therapy is limited.
