Therefore, it is advisable to check whether the size of the estimated regression coefficient differs between these different study designs.
This difference may be due to different study designs and populations.
However, there were differences in the summary RR among different study designs.
Differing results across studies may be due to different study designs, emission levels, and exposure misclassification.
This difference may well be a consequence of the different study designs (in vitro versus in vivo).
The differences in the results between the two studies may, therefore, be due to different study designs and patient collectives.
Such a condition might not be met for different study designs.
Besides RCTs, other relevant studies with different study designs were included.
Different study designs, with controversial end-point choices, do not allow a direct comparison of the trials' results.
This may be due to different health systems in general, to different referral systems and to different study designs.
All results remained consistent across different study designs, valganciclovir doses, and CMV serostatus.
