Association between numbers of F4/80⁺ cells in crescents and those in peripheral blood and interstitium^†.

F4/80+ cells	Correlation coefficients‡	P-values
Peripheral blood§	0·595	0·039
Interstitium¶ (cortex)	0·305	n.s.
Interstitium¶ (medulla)	0·544	n.s.

^†Number of mice: eight.

^‡Strength of association between F4/80⁺ cells within crescents and those in peripheral blood or interstitium is expressed as Pearson's correlation coefficients (r) and P-values. n.s. = not significant.

^§Numbers of F4/80⁺ cells in peripheral blood at the onset of glomerulonephritis (GN) (/μl).

^¶Numbers of F4/80⁺ cells in 10 randomly selected high-power fields.
