Two key factors affected the strength of evidence: potential risk of bias in the included studies and sparsity of data for many of the outcomes and comparisons, which resulted in imprecise estimates and unknown consistency of estimates across studies.
Additionally, a study in the elderly can also serve as a control group for case-control comparisons, which overcomes many of the usual challenges of control group identification: Control groups in genetic studies are often enriched for other diseases, e.g. by recruiting from hospitals, or are substantially younger or from a different region or even country than the patient group.
Fig. 12 Replication w/ standard partitioning vs. replication w/ overlapped partitioning, using replication factor 3. Meshed Partitioning splits the task in more than one dimension and provides many points of comparison, which are then used to decide on the correctness of a result.
Then in February it formally announced its new photo viewer design that shows comments and ads in the right sidebar rather than beneath photos, which drew many comparisons to the Google+ photo viewer.
When many comparisons were made among the variables, there was a chance for the P-value, which is related with each individual comparison, to be underestimated.
Importantly, these data were collected as part of a multi-species comparison, which included many sites in types of habitats from which P. cespitosum was absent, and therefore, any measured increase in ecological range between years was not likely due to incomplete sampling in 1994.
I'm already seeing many, many comparisons to Gangnam Style.
Many comparisons have been made between the two presidents recently.
