In a ________ model, the underlying assumption is that a single true effect size underlies all study results and that observed estimates vary only as a function of chance.
fixed effects

A _______ model assumes that each study estimates different, yet related, true effects and that the various effects are normally distributed around a mean effect size value.
random effects

________ involve splitting the effect size information from studies into distinct categorical groups (ex: gender).
subgroup analyses

In a systematic review, reviewers use methodocial procedures that are ______ and ______.
reproducible and verifiable

In a _______, reviewers use a common metric for combing evidence statistically.
metaanalysis

Three advantages of metaanalyses.
 objectivity
 precision
 power

The probability of detecting a true relationship b/w variables.
power (advantage to metaanalysis)

Estimates of effect size across most studies yield smaller CI's than individual studies. How does this affect precision?
It is enhanced

A means of refining the specific question for the systematic review.
Scoping review

The preliminary investigation that clarifies the range and nature of the evidence base.
scoping review

A ______ review addresses broad questions and uses flexible procedures.
scoping

The inverse variance method uses the inverse of the variance of the __________ as weight.
effect size estimate

_______ across studies may rule out the possibility that a metaanalysis can be done
heterogeneity

How can visual inspection of heterogeneity be accomplished?
by constructing a forest plot

A random effects metaanalysis incorporates heterogeneity into the analysis, but is intended primarily to address what?
variation that cannot be explained

________ analyses involve splitting the effect size information from studies into distinct categorical groups (ex: gender).
subgroup

What might be appropriate when variables thought to influence study heterogeneity are continuous or there is a mix of continuous and categorical factors?
metaregression

_______ involves predicting the effect size based on possible explanatory factors.
metaregression

What is the most usual way to examine the possibility of publication bias among studies in the metaanalysis?
construct a funnel plot

In a _____, effects from individual studies are plotted on the horizontal axis and precision is plotted on the vertical axis.
funnel plot

A strategy for addressing publication bias in metaanalysis.
compute a failsafe number

What estimates the number of studies reporting nonsig results that would be needed to reverse the conclusion of a significant effect in a metaanalysis?
failsafe number

Involves carefully peeling away the surface layers of studies to find their hearts and souls in a way that does the least damage to them.
Metasynthesis

Noble & Hare's methods of integration are called _________.
metaethnography.

A metaethnography should be _____ and not ___ and should focus on constructing ____ rather than _______.
 interpretive
 aggregative
 interpretations
 analyses

What is the Paterson, Thorne, Canam, and Jillings method of metasynthesis?
Metastudy

Metastudy's 3 components.
 metadata analysis
 metamethod
 methatheory

The study of results of reported research in a specific substantive area of investigation by means of analyzing the processed data.
Metadata analysis

The study of the methodologic rigor of the studies included in the metasynthesis.
Metamethod

The analysis of the theoretical underpinnings on which the studies are grounded.
Metatheory

Indicates the magnitude of the findings.
Frequency effect size

Number of reports with unduplicated info that contain a given finding, divided by all unduplicated reports.
Frequency effect size

Indicates the concentration of findings within each report.
intensity effect size

Calculated by dividing the number of different findings in a given report, divided by the total number of findings in all reports.
intensity effect size

__________ reviews use disciplined and auditable procedures to integrate and synthesize findings from qual, quant, and mixed methods.
systematic mixed studies

Three designs of systematic mixed studies reviews.
 segregated
 integrated
 contigent

Two common effect size indexes in nursing.
 d (standardized mean difference)
 odds ration

Effects from individual studies are pooled to yield an estimate of the population effect size by calculating a _______ of effects, often using the _________ as the weight.
 weighted average
 inverse variance

The two reporting guidelines  one for RCTs, one for metaanalyses of observational studies.
 PRISMA (RCT)
 MOOSE (observational)

_________ involve a discovery of essential features of a body of findings and a transformation that yields new insights and interpretations.
Metasyntheses
