Slope at year(s)Delayed treatment group (n = 78)Early treatment group (n = 75)p Value
Slope 0–1 year: based upon radiographs at study entry, 6 months, and 1 year; slope 0–2 years: based upon radiographs at study entry, 6 months, 1, and 2 years; slope 0–4 years: based upon radiographs at study entry, 6 months, 1, 2, 3, and 4 years; slope 1–4 years: based upon radiographs at 1, 2, 3, and 4 years; slope 2–4 years: based upon radiographs at 2, 3, and 4 years.
