1 · What the graph read from 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.

2 · The registry

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

purposeIron deficiency anemia is common in colorectal cancer patients and is related to poor surgical outcome. Increasing evidence supports preoperative use of intravenous iron (IVI) to correct anemia. Our study investigates effect of preoperative IVI on hemoglobin level.

methodsFrom August 2017 to March 2019, colorectal cancer patients with iron deficiency anemia received intravenous iron at least 2 weeks before their scheduled operations (IVI group). These patients' prospectively collected data were compared to a historic cohort of anemic patients who received elective colorectal surgery within 3 years before the study period (non-IVI).

resultsForty-six patients were included after receiving intravenous iron. After propensity score matching on 1:2 ratio, 38 patients in IVI group were matched with 62 patients from non-IVI group. There was no statistical difference for preoperative mean hemoglobin level between the two groups (8.43 g/dL in IVI, 8.79 g/dL in non-IVI, p = 0.117), but IVI group has significantly higher mean hemoglobin level on admission (10.63 g/dL in IVI, 9.46 g/dL in non-IVI, p = < 0.001). IVI group had higher median hemoglobin rise (1.9 in IVI, 0.6 in non-IVI, p = <0.001) and significantly less red cell transfusion (8 patients in IVI, 30 in non-IVI, p = 0.006). Subgroup analysis showed that less patients in IVI group required transfusions in preoperative period (1 in IVI group, 20 in non-IVI, p < 0.001).

conclusionOur data suggested that IVI can significantly increase hemoglobin level in iron deficiency anemic patients before colorectal surgery, with reduction in red cell transfusions.
