Data reflect sole-focus businesses only.

(A) Breakdown of employees by qualification (n = 130). “Other medical qualification” category includes Doctor of Podiatric Medicine (n = 1), physical therapists (n = 1), physician assistants (n = 5), and nurse practitioners (n = 2). Seven individuals listed non-medical graduate degrees, and a further three did not specify their qualifications. Two of the sole-focus businesses did not provide any information regarding practice employees or care providers.

(B) Relationship between practitioner specialty and stem cell source, stem cell type, and medical conditions treated. Data are shown as the percentage of practitioners with an indicated specialty who use a specific stem cell source or stem cell type as well as treat a specific medical condition.

(C) Relationship between stem cell source/type and medical condition treated. Data are shown as the column-normalized, relative frequency with which a specific condition is treated with a particular stem cell source/type. Analysis is based on information stated on stem cell business websites. A single business may use more than one cell type and cell source, and offer to treat more than one condition. Multiple care providers may also practice within a given business.
