Figure 4. Effect of vitamin B12 and folic acid on change in daily life functions. The daily life functions were not significantly different between the pooled treatment and control groups in either ADL (MD = −0.04, 95% CI = −0.31 to 0.23, p = 0.79), IADL (MD = 0.31, 95% CI = −0.32 to 0.94, p = 0.34), or ADCS-ADL (MD = −0.05, 95% CI = −0.25 to 0.14, p = 0.60).
