Linear regression analyses of disaturated phosphatidylcholine (DSPC) content in lung tissue (A) and surfactant (B) and of protein in surfactant (C) as a function of body weight in 8-week-old rats (total 32; control 19; obese, 13). PLPi, phospholipid phosphorus. The regression equations are, for A, f(x) = 5.238459E−1*x + −2.318764E+0, R2= 0.63; for B, f(x) = 1.782022E−2*x + 1.086841E+1, R2 = 0.05; for C, f(x) = −4.003834E−1*x + 6.230710E+2, R2 = 0.009. The p values for correlation are, for A, <0.001; for B, = 0.19; and for C, = 0.60. There is weak correlation (r = 0.79) of body weight for lung tissue DSPC content.
