A fraction such as “3/12” is how CDC reports a rate when fewer than 20 cycles stand behind it. An asterisk (“*/9”) means CDC suppressed a count of 1–4 to protect patient privacy. CDC cautions that comparing clinics' success rates may not be meaningful, because patient populations and treatment methods differ between clinics — how to read these numbers.

These are CDC's figures for 2022, published exactly as reported. They describe this clinic's past patients, not your personal chance — which depends on your age, diagnosis and history. CDC cautions that comparisons between clinics may not be meaningful. How to read them.
