Fig. 2. From: Identification of biochemical differences between different forms of male infertility by nuclear magnetic resonance (NMR) spectroscopy.

Cross validated scores plot constructed from the OPLS-DA model of seminal plasma 1H NMR profile of fertile control population (red dots) and idiopathic infertile groups (black squares). Model details: R2Y = 0.73 and Q2 (cum) = 0.61. Each point (dots or square) represents the seminal plasma 1H NMR spectral profile from a single individual

Fig. 4. From: Identification of biochemical differences between different forms of male infertility by nuclear magnetic resonance (NMR) spectroscopy.

Cross validated scores plot constructed from the OPLS-DA model of seminal plasma 1H NMR profile of idiopathic infertility patients (orange dots) and all other infertile groups (blue squares). Model details: R2Y = 0.60 and Q2 (cum) = 0.50. Each point (dots or square) represents the seminal plasma 1H NMR spectral profile from a single individual

Fig. 3. From: Identification of biochemical differences between different forms of male infertility by nuclear magnetic resonance (NMR) spectroscopy.

Cross validated scores plot constructed from the OPLS-DA model of seminal plasma 1H NMR profile of fertile control population (red dots) and oligozoospermic infertile groups (black squares). Model details: R2Y = 0.89 and Q2 (cum) = 0.68. Each point (dots or square) represents the seminal plasma 1H NMR spectral profile from a single individual

The correlation of cross validated scores of two OPLS models with normalized peak intensity of lysine at 1.74 ppm. (a). idiopathic infertility (orange dots) and all other infertile groups (blue squares). Model detail: R2Y = 0.99 and Q2(cum) = 0.97, Equation of the regression line: normalized intensity of lysine (1.74 ppm) = 0.015 * cross validated scores of OPLS model + 0.014. (b). Idiopathic infertility (black squares) and fertile control population (red dots). Model detail: R2Y = 0.98 and Q2 (cum) = 0.98. Equation of the regression line: normalized intensity of lysine (1.74 ppm) = 0.012 * cross validated scores of OPLS model + 0.011
