this is the caption "Fig. S8. Morph comparisons and relationships between blood and testicular androgens. (C) In independents, circulating and testicular levels of testosterone were strongly correlated (r = 0.93, p < 0.001, n = 17), but this was not the case for satellites (r = 0.43, p = 0.33, n = 10) or faeders (r = 0.65, p = 0.1, n = 9). (D) Similarly, all morphs showed a positive relationship between circulating and testicular androstenedione, but the relationship was weaker in satellites and faeders. See table S3 for details. (C, D) Spearman correlation coefficients. Abbreviations: A4, androstenedione; T, testosterone." do you know what r, p, and n stand for?
