Sensitivity analysis is the study of how the uncertainty in the output of a mathematical model or system (numerical or otherwise) can be divided and allocated to different sources of uncertainty in its inputs. A related practice is uncertainty analysis, which has a greater focus on uncertainty quantification and propagation of uncertainty; ideally, uncertainty and sensitivity analysis should.

The literature search was conducted according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) [].The screening process and results are shown in Fig. 1.We conducted a systematic electronic literature review using PubMed in November 2017, and we updated it in March 2018 and again in August 2018.

Knapp & Hartung Adjustment is turned off by the default in the metafor package. The Knapp and Hartung (2003) method is an adjustment to the standard errors of the estimated coefficients, which helps to account for the uncertainty in the estimate of the amount of (residual) heterogeneity and leads to different reference distributions.

Only two associations remain when we perform a sensitivity analysis in the subset of never. For each of the eight regressions, we performed a sample-size-weighted meta-analysis of the cohort-level.

“Although my centre develops the statistical software the whole Cochrane Collaboration uses for its systematic reviews and meta-analyses (Review Manager), I have often used Comprehensive Meta-Analysis for my own research projects, as it is easy to import data from Excel, to use effect modifiers, and also because it allows meta-regression and produces bubble graphs that are easy to work with.
