marginal significancep = 0.0066
In the Static Functional Index, the Toe Spread Factor (TSF), which is the measurement from toes 1 to 5, is the most significant ( p < 0.0001), followed by the intermediary toe spread (ITS) factor (toes 2 to 4), which has near marginal significance ( p = 0.0066), and it excludes the print length (PL) factor, due to its high variability and statistical insignificance ( p = 0.3362).
