Iron Replacement in Patients with Inflammatory Bowel Disease: A Systematic Review and Meta-analysis.
Synthesis in Inflammatory bowel diseases, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis 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
backgroundA number of controlled trials and prospective studies have compared intravenous (IV) to oral (PO) iron for the treatment of iron deficiency anemia with mixed results.
methodsWe conducted a systematic review of trials published on 2014 that compared IV with PO iron to treat in patients with IBD. Meta-analysis was performed to generate effect estimates. Quality assessment was also performed according to GRADE criteria.
resultsFive studies met our inclusion criteria, enrolling 694 patients. For the primary outcome of "response" (hemoglobin rise >2 g/dL), there was no significant difference between IV or PO iron; risk ratio for response with IV was 1.08 (95% CI, 0.9-1.2; P = 0.2). For the secondary outcome of mean change in hemoglobin (g/dL), the mean difference between PO and IV iron was not statistically significant (mean difference, 0.6 g/dL, 96% CI, -0.1 to 1.3; P = 0.08). IV iron was associated with a significantly greater initial rise in serum ferritin compared with PO iron (mean difference 89 ng/mL; 95% CI, 29-148, P = 0.003). There was a lower risk of withdrawal due to adverse events in these trials in the IV iron cohorts when compared with PO iron (risk ratio, 0.4; 95% CI, 0.1-1.0; P = 0.05).
conclusionsWe found no significant difference between IV and PO iron in correcting iron-deficiency anemia in patients with IBD in this meta-analysis. Patients who received IV iron had a greater rise in serum ferritin and were less likely to stop treatment due to adverse events, when compared with those who received PO iron.
