Iron deficiency anemia in infants in Sousa (PB), Brazil: an association with nutritional status.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe aim of this study was to describe the prevalence of anemia and iron deficiency anemia (IDA) in infants and verify the association of iron deficiency with nutritional status.
methodsThis cross-sectional and observational study included 104 infants aged between 7 and 9 months, assisted from August to September 2021 by the Family Health Strategy program in Sousa municipality (Paraíba, Brazil). Clinical and anthropometric data were collected, and a 24-h food recall questionnaire was applied using the DietPro software (version 5.0) in order to verify food consumption and assess iron intake. Variables associated with iron deficiency (p<0.05) were analyzed using multiple logistic regression.
resultsAnemia and IDA were observed in 40.4% and 19.2% of infants, respectively. Only one infant was taking prophylactic supplementation (ferrous sulfate). Infants with IDA presented reduced hemoglobin (p<0.001) and ferritin (p<0.001) and increased Z-scores of body mass index-for-age (Z-BMI) (p=0.027), weight-for-height (p=0.007), and weight-for-age (p=0.032). All Z-scores were inversely correlated with ferritin (Z-BMI [rho: -0.37; p<0.001], weight-for-height [rho: -0.37; p<0.001], and weight-for-age [rho: -0.29; p=0.002]). Ferritin was also directly correlated with daily iron intake (rho: 0.22; p=0.018). Finally, multiple logistic regression showed a significant and direct association of iron deficiency with weight-for-height Z-score (odds ratio: 2.86; 95% confidence interval: 1.38-5.64; p=0.004).
conclusionAbout 60% of infants presented anemia or IDA. Iron deficiency was associated with the weight-for-height Z-score, showing the vulnerability of infants during the introduction of complementary feeding.
