Objective: To summarize current evidence on the potential cross‐sectional and longitudinal association between meaning or purpose in life and subjective happiness or life satisfaction among cancer patients. Methods: A systematic review with meta‐analysis and meta‐regression was conducted. CINAHL (via ...
“Our meta-analysis has some limitations. First, the absence of patient-level data prevents assessment of many baseline characteristics related to safety and efficacy outcomes. Second, different cohorts of patients (ie, acute corona...
with more than two variables, at regional, country, or other levels), the coefficient of determination is reduced by 2.1 pp in U_dep and 4.2 pp in Y_dep, meaning that 2.1% of the variation of the dependent variables is no longer explained by the regression model with the U_dep databas...

the same underlying population, meaning that these models can be used when different studies are likely to quantify different underlying mean effects (for example, one study design yields a different effect than another), as is likely to be the case for a biological meta-analysis (Fig. 4b). ...
(I2 = 34.9%, P = 0.19). The result was still robust after jack-knife analysis. No significant publication bias was found using Egger’s test (coefficient = −1.50; P = 0.23). We performed a meta-regression to explore the likely source of heterogeneity and found that...
We calculated the risk of publication bias using funnel plots and Egger's regression test (Egger et al., 1997). In the presence of publication bias, the funnel plot becomes asymmetrical, and Egger's test has significant statistic values. Results Sample characteristics This meta-analysis included ...

Binary end points were analyzed using log binomial regression in a generalized estimating equations model with an exchangeable correlation structure to account for multiple births. Models were adjusted for trial as a fixed effect because the methods used for the prospective meta-analysis meant all 5 ...
