Lines represent the interventions. Columns represent the health conditions where the searched outcome has been considered. Quality of evidence was reported into each cell with the following acronyms: VL: very low-quality; L: low-quality; M: moderate-quality; H: high-quality; Na: not available. *Effect in favor of the intervention; **no definite results.
