Safety of Intravenous Iron in CKD Stage 3-5 Patients Not on Dialysis: A Retrospective Cohort Study.
Article in Canadian journal of kidney health and disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Iron deficiency is common in chronic kidney disease (CKD) patients not on dialysis (ND). Restoring depleted iron stores through intravenous (IV) route is faster and associated with less side effects. There is conflicting data regarding intravenous iron use and its impact on clinical outcomes in this population. Objective: This study aims at evaluating any negative clinical impact associated with IV iron use in CKD patients at stages (3-5) before dialysis. Design: Retrospective chart review. Setting and Population: Chart analysis of ND CKD 3-5 (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73 m Methods: Outcomes analyzed were rates of all-cause hospitalizations, infection-related hospitalizations, mortality rates, and eGFR decline over 12 months after IV iron infusion in this population divided into 3 groups according to CKD stage. Results: A total of 738 patients were included in our analysis. Mean initial hemoglobin concentration was 111.5 ± 15.0 g/L in group 1 (CKD 3: eGFR 30-59 mL/min/1.73 m Limitations: Lack of control group, retrospective study. Conclusion: Intravenous iron use in CKD 3-5 ND is generally safe. Higher hospitalization rates in patients with eGFR <30 mL/min are possibly associated with lower baseline hemoglobin, lower baseline eGFR, and higher comorbidity burden, and not related to iron infusion.
