Seminario “Systematic reviews including non-randomised studies”

For some Cochrane reviews, the question of interest cannot be answered by randomized trials, and review authors may be justified in including non-randomized studies. Potential biases are likely to be greater for non-randomized studies compared with randomized trials, so results should always be interpreted with caution when they are included in reviews and meta-analyses. Particular concerns arise  with respect to differences between people in different intervention groups (selection bias) and studies that do not explicitly report having had a protocol (reporting bias). Meta-analyses of non-randomized studies must consider how potential confounders are addressed, and consider the likelihood of increased heterogeneity resulting from residual confounding and from other biases that vary across studies.
