Responses to salt stress of nitrogen (a), phosphorus (b), potassium ion (c), sodium ion (d), calcium ion (e), and magnesium ion (f) in AMF-inoculated halophytes and glycophytes. Error bars represent 95% confidence intervals (CIs). Back-transformed effect sizes are shown above the bars. The numbers of studies are shown under the bars. Inoculation effects were considered significant when the 95% CIs did not overlap with zero. The P values for each panel reflect the significant differences between halophytes and glycophytes
