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
backgroundRecent clinical guidelines suggest that treatment of postoperative anaemia in colorectal cancer surgery with intravenous iron reduces transfusion requirements and improves outcomes. The study aimed at comparing two intravenous iron regimens in anaemic patients after colorectal cancer surgery. MATERIALS AND
methodsThis was a single-centre, open-label, randomised, controlled trial in patients undergoing elective colorectal cancer surgery. Patients with moderate to severe anaemia (haemoglobin [Hb] <11 g/dL) after surgery were randomly assigned 1:1 to receive ferric carboxymaltose (FC; 1,000 mg, single dose) or iron sucrose (IS; 200 mg every 48 hours until covering the total iron deficit or discharge). Randomisation was stratified by Hb level: <10 g/dL (Group A) or ≥10-10.9 (Group B). The primary endpoint was the change in Hb concentration at postoperative day 30. Secondary endpoints included iron status parameters, transfusion requirements, complications, and length of hospital stay.
resultsFrom September 2015 to May 2018, 104 patients were randomised (FC 50, IS 54). The median intravenous iron dose was 1,000 mg and 600 mg in the FC and IS groups, respectively. There were no between-group differences in mean change in Hb from postoperative day 1 to postoperative day 30 (FC: 2.5 g/dL, 95% CI: 2.1-2.9; IS: 2.4 g/dL, 95% CI: 2.0-2.8; p=0.52), in transfusion requirements or length of stay. The infection rate was lower in the FC group compared with the IS group (9.8% vs 37.2%, respectively). DISCUSSION: The administration of approximately 500 mg of IS resulted in an increase in Hb at postoperative day 30 similar to that of 1,000 mg of FC, but it was associated with a higher infection rate. Future research will be needed to confirm the results, and to choose the best regime in terms of effectiveness and side effects to treat postoperative anaemia in colorectal cancer patients.
