Meta-analysis approach on iron fortification and its effect on pregnancy and its outcome through randomized, controlled trials.
Review in Journal of family medicine and primary care, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 5 of them syntheses that pooled it.
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
Micronutrients' deficiency is a common phenomenon among a majority of the population residing in the low- and middle-income countries (LMICs) especially among women and children. Given the widespread prevalence of micronutrients' deficiency in LMICs, iron-fortified foods could be of potential benefits for both the mother and the development of fetus. Present study aims to provide the evidence on the impact of iron fortification on hemoglobin (Hb) concentration during pregnancy and evaluates the specific maternal and pregnancy outcomes. We conducted systematic review by using search engines such as PubMed, Cochrane Library, Medline, EMbase, and secondary references. Meta-analyses were performed to calculate summary estimates on Hb during pregnancy, low birth weight (LBW), and preterm births. The weighted mean difference (WMD) and relative risk (RR) were calculated using random-effects models. Sources of heterogeneity were explored through meta-regression. Eight studies were included for the final analysis. The overall pooled estimate of Hb showed a significant increase in the fortification group compared with the control group [WMD = 4.45 g/L; 95% confidence interval (CI) = 2.73, 6.17 g/L;
