Figure 29 displays a forest plot of studies reporting pain intensity using the Visual Analogue Scale, magnesium sulphate vs. placebo. Three studies reported pain intensity. The pooled analysis showed a statistically significant difference favoring magnesium sulphate over placebo (MD = −9.73, 95% CI: −16.75, −2.72; I2 = 0%).
