Figure 6
Reduction in all-cause and CHD-related infant mortality following the introduction of Hridyam programs in Kerala. By the non-parametric Mann Whitney U test, this improvement is of borderline statistical significance (p = 0.06), probably due to the small sample size of comparing data from two Hridyam years to four pre-Hridyam years.
