Standardized major axis (SMA) regression slopes and confidence intervals (CI) for log-log transformed relationships between plant height and leaf length of Leymus chinensis (Trin.) Tzvelev in grazing exclusion and grazing groups.

Symbols**, P *, P NS, P > 0.05.Abbreviations are the same as those in Fig 1 and Table 1.95% CI of SMA slopes, intercepts, and common slopes are shown. In several bivariate cases, SMA tests for common slopes revealed no significant differences between the two groups (i.e., P > 0.05). In such cases, common slopes and CIs for the bivariate relationships are shown. Significant shifts along a common slope are indicated.
