Weak but consistent evidence for a protective effect for haplogroup E1b1b1c was seen in all studies with a nominally significant meta-analysis, thus, calling for additional replication efforts for this haplogroup in populations of Ashkenazi Jewish and European ancestry.
NS: not significant Meta-analysis, a quantitative technique for therapeutic evaluation, may be used when controversy persists after several trials.
Our methods require a non-significant meta-analysis as a starting point, therefore if a simulated meta-analysis showed a significant pooled estimate, it was discarded and a new one was simulated.
If the goal is instead to decide whether a given non-significant meta-analysis is up to date, we can diagnose the meta-analysis as being out of date when the new participant ratio is greater than some threshold q, say q = 1.
This paper focuses specifically on interventions which are evidenced by a statistically significant meta analysis or where the intervention is supported by a generally positive trend of results when a meta analysis was not possible.
Reviews reporting on effective interventions were those which presented a statistically significant meta analysis or where the intervention was supported by a generally positive trend of results when a meta analysis was not possible to ensure the recommendations of the paper are based on strong evidence of good quality.
ameans statistically significant A meta-analysis of 106 reports on femoral neck fractures [ 22] revealed that the nonunion rate was 33%% and the rate of avascular necrosis was 16 % after internal fixation of displaced femoral neck fractures.
Our paper is the first known to show a significant association in a meta-analysis of populations of European descent, although both previous meta-analyses found a nonsignificant trend toward an association in a dominant model (26, 91).
