Loneliness in different age groups.

<p>Prevalence of perceived frequency of loneliness by 5-year age groups.</p

Relative effect sizes (and 95% credibility intervals) of psychotherapeutic interventions and control conditions from conventional meta-analysis (upper triangle) and network meta-analysis (lower triangle).

<p>Dashes indicate pairs of conditions that have not been compared in a study. Negative signs in the upper triangle indicate superiority of the condition in column; negative signs in the lower triangle indicate superiority of the condition in the row. Significant effects are printed in bold.</p>a<p>These confidence intervals are calculated by method of moments random effects meta-analysis.</p>b<p>If only a single comparison was present no credibility intervals are presented.</p><p>n.e., not estimated.</p
