The trade: Different divisions, so this is the trade, not a verdict. Tirzepatide loses about 9 more points of body weight. Orforglipron adds convenience: a daily pill instead of a once weekly injection, no cold chain, supply that scales. If maximum loss matters most and an injection is acceptable, Tirzepatide; if avoiding the needle matters more, Orforglipron.
Standalone, this page carries its own key: Efficacy = % body weight lost vs placebo, on the conservative estimand that counts everyone. Tolerability = AE-discontinuation over placebo (Mild 1 to 5 · Notable 5 to 10 · Heavy over 10 points). Different divisions, so efficacy is shown as raw magnitude, not a verdict. The side marked leads or gentler wins that axis.
