Gemini 3.6 Flash1,347 words
As CEO, my fundamental leadership principle in a crisis of this magnitude is: You cannot manage a crisis until you accept the full cost of doing the right thing. A safety issue of 1 in 8,000 patients over 5 years across a 4-million-patient population represents approximately 500 potential cases of liver failure.
