Study network. The study network presents sharp connections between placebo vs. GLP1-RA, placebo vs. SGLT2i, placebo vs. DPP4i and placebo vs. TZD (pioglitazone). The nodes for Sulfonylurea, TZD, DPP4i, GLP1-RA, SGLT2i are also tightly connected with most treatment arms, however, it is possible to observe a poor connection between drug combinations (SGLT2i+GLP1-RA, GLP1-RA1+Insulin, SGLT2i+DPP4i, GLP1-RA+TZD, etc) and other treatment arms. By using additive component network meta-analysis, it is possible to account for both single treatments and combinations, but the combinations may be more prone to depend on the effect of indirect comparisons if paralleled to single treatment comparisons.
