Kulkarni et al. iron deficiency and anemia comparison

	A	B	C	D	E
1			Value	Source	Notes
2	1 to 4 year-olds
3		Proportion of individuals with iron deficiency (serum ferritin adjusted with modified BRINDA)	31.9%	Kulkarni et al. 2021	Pg 2428, Table 2. The table also presents iron deficiency prevalence estimates using different inflammation adjustment methods. We've focused on serum ferritin adjusted with modified BRINDA because this is the method Kulkarni et al. 2021 use when presenting their headline results: "ID prevalence was higher in 1- to 4-y-old children (31.9%; 95% CI: 31.0%, 32.8%) and adolescent girls (30.4%; 95% CI: 29.3%, 31.5%) but lower in adolescent boys and 5- to 9-y-old children (11%–15%)." Pg 2422.
4		Proportion of individuals with anemia	40.6%	Kulkarni et al. 2021	Pg 2428, Table 2.
5		Proportion of individuals with anemia who also have iron deficiency (assuming full overlap)	79%	Calculation
6
7	5 to 9 year-olds
8		Proportion of individuals with iron deficiency (serum ferritin adjusted with modified BRINDA)	15.5%	Kulkarni et al. 2021	Pg 2428, Table 2.
9		Proportion of individuals with anemia	23.6%	Kulkarni et al. 2021	Pg 2428, Table 2.
10		Proportion of individuals with anemia who also have iron deficiency (assuming full overlap)	66%	Calculation
11
12	10 to 19 year-old boys
13		Proportion of individuals with iron deficiency (serum ferritin adjusted with modified BRINDA)	11.5%	Kulkarni et al. 2021	Pg 2428, Table 2. We present separate estimates for boys and girls aged 10 to 19 because there appears to be a substantial divergence in results by gender at that age group (see Table 2).
14		Proportion of individuals with anemia	17.7%	Kulkarni et al. 2021	Pg 2428, Table 2.
15		Proportion of individuals with anemia who also have iron deficiency (assuming full overlap)	65%	Calculation
16
17	10 to 19 year-old girls
18		Proportion of individuals with iron deficiency (serum ferritin adjusted with modified BRINDA)	30.40%	Kulkarni et al. 2021	Pg 2428, Table 2.
19		Proportion of individuals with anemia	40.50%	Kulkarni et al. 2021	Pg 2428, Table 2.
20		Proportion of individuals with anemia who also have iron deficiency (assuming full overlap)	75%	Calculation
