In a forest plot, the diamond represents the pooled effect estimate from meta-analysis, and when it touches the line of no effect, it indicates the overall result is not statistically significant. But I must disagree with the quiet conclusion some draw from this—a diamond touching the line does not mean the policy intervention is worthless. In my work evaluating a community nutrition scheme here, the pooled estimate once showed no significant effect, but our field visits revealed profound localised improvements the aggregate diamond had smoothed away. The forest plot gives one truth, baba, but the real effect is often in the *kichhu* details the single diamond cannot hold.
