We considered statistically significant an adjusted threshold of P < 0.003, after applying Bonferroni correction for multiple comparisons.
Multiple health care types: RCTs with patient health outcomes: chronic and acute care (n = 1); chronic and preventive care (n = 2), RCTs with health services outcomes: chronic and acute care (n = 7); chronic and preventive care (n = 3); chronic, acute, and preventive care (n = 2).
Multiple types of intervention: behavioural intervention (on patients) and intervention on structure (n = 1); behavioural intervention (on patients) and a drug (n = 2).
