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

backgroundEvidence on the role of intravenous iron (IVI) supplementation after colorectal cancer (CRC) surgery is rather scant. This study was aimed at assessing the benefit of post-operative IVI administration after elective CRC surgery at our institution. MATERIALS AND

methodsThis was a single-centre, retrospective observational study including all patients who underwent CRC surgery during 2014. Anaemia was defined as a haemoglobin (Hb) <13 g/dL, regardless of gender. Anaemic patients received 200 mg IVI up to three times a week to cover iron deficiency (IVI group). Those who did not receive IVI were placed on standard care (NIVI group). The primary outcome was the proportion of anaemic patients on post-operative day (POD)1 and POD30. Secondary outcomes included Hb changes from POD1 to POD30, transfusion requirements and complication rates.

resultsOf the 159 patients studied, 139 (87%) presented with anaemia: 47 (34%) of these received post-operative IVI and 92 (66%) did not. Patients in the IVI group had lower POD1 Hb levels compared to those in the NIVI group (p=0.001). On POD30, only 103 had their Hb measured (34 IVI, 69 NIVI). Anaemia was more prevalent and more severe among the patients in the IVI group (p=0.027), despite their greater increment in Hb (2.0±1.5 g/dL vs 1.1±1.2 g/dL; p=0.001). Eleven patients needed post-operative transfusions (7 IVI, 4 NIVI; p=0.044). There were no differences in post-operative complication rates between the groups. No IVI-related adverse events were recorded DISCUSSION: Compared with standard care, post-operative IVI administration to anaemic patients improved the recovery of Hb levels at POD30, without increasing post-operative complications.
