The highest number of matched guidelines was for one meta-analysis in non-small cell lung cancer, for which 16 matched guidelines were identified.
For one meta-analysis only one trial had no exclusions from the analysis, and no between trial heterogeneity could be estimated after the restriction.
Therefore we simulated series of trials with two up to 20 studies, where each series provided the data for one meta-analysis.
For example, the pooled results of one meta-analysis that included 31 randomized control trials indicated a reduction of risk of recurrence of breast cancer after chemotherapy, in contrast to no chemotherapy, while the individual result of each trial was inconclusive [ 43].
As can be seen, SMD reductions in depressive symptoms included non-overlapping confidence intervals for both with one meta-analysis yielding a small SMD [ 37] and one yielding a medium SMD [ 30].
For example, in one meta-analysis, the miR-146a*C variant (rs2910164) and miR-196a-2*T miR-196a-2*T miR-196a-2*T the genes encoding mirs11614913 miR-196a-2, respecontainedwere shown to decrease the rink and increase the susceptibility to HCC, respectively [[ 37]].
For example, one meta-analysis estimated that adding caffeine to analgesics significantly increased the number of patients who experienced nervousness and dizziness (relative risk 1.60) [75].
For example, one meta-analysis reported a small, but significantly increased risk of serious adverse cardiovascular events in users of varenicline.
For LGG, one meta-analysis of eight RCTs, involving 988 participants, found that compared with controls, administration of LGG had no effect on the total stool volume.
For smectite, one meta-analysis of data from six RCTs showed that smectite significantly reduced the duration of diarrhea compared with placebo.
For example, one meta-analysis of team-training that included 93 effect sizes across a broad range of industries found that participation in team-training can account for nearly 20% of the variance in team processes (ρ=0.44) and outcomes (ρ=0.39).
