Status of Iron Metabolism 10 Years After Roux-En-Y Gastric Bypass.
Article in Obesity surgery, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 papers, 3 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
backgroundThe aim of this study is to investigate changes in iron metabolism and verify whether biochemical parameters are related to the use of oral iron supplement 10 years after Roux-en-Y gastric bypass.
methodsThis longitudinal retrospective study included 151 patients submitted to Roux-en-Y gastric bypass. The collected data included use of an oral iron supplement, hemoglobin, hematocrit, serum iron, and ferritin. The chi-squared or Fisher's exact test was used to analyze the association between use of iron supplement and nutritional deficiency. The generalized estimating equations (GEEs) analyzed the nutritional deficiencies over time.
resultsOf the study patients with iron-deficiency anemia (n = 15) in the 12-month follow-up, 73.33% (n = 11) were taking an iron supplement, and 26.67% (n = 4) were not (p = 0.0010). The effect of time was significant for hemoglobin, ferritin, iron overload (p < 0.0001), and hematocrit (p = 0.0007). Of the patients who remained in the study until the 120-month follow-up, 37.5 and 45.0% were diagnosed with iron-deficiency anemia, defined as ferritin <15 μg/L and ferritin <30 μg/L, respectively.
conclusionsIron-deficiency anemia increased over time even in patients taking oral iron supplements.
