Impact of Preoperative Anemia on Outcomes of Enhanced Recovery Program After Colorectal Surgery: A Monocentric Retrospective Study.
Article in World journal of surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundAnemia is common before major abdominal surgery (35%). It is an independent factor for postoperative complications and longer length of stay (LOS). The aim of this study was to evaluate the extent to which preoperative anemia impacts on enhanced recovery programs (ERP) outcomes. MATERIALS AND
methodsThe data for patients scheduled for colorectal surgery between 2015 and 2019, were analyzed (n = 494). All patients were managed with the same ERP. Demographic data, preoperative risk factors, postoperative complications, LOS and adherence to ERP were compared between anemic and non-anemic patients. Anemia was defined by a hemoglobin concentration < 13 g dL RESULTS AND DISCUSSION: In total, 173 patients had preoperative anemia. They were older (p < 0.001) and more often male (p = 0.02). The following risk factors were significantly more frequent in the anemic group: renal failure (p = 0.04), malnutrition (p < 0.001), cardiac arrhythmia (p < 0.001), coronaropathy (p = 0.02) and anticoagulant treatment (p < 0.001). Despite more risk factors, anemic patients did not experience more postoperative complications (38.2% vs. 31.2%, p = 0.12). Overall adherence to ERP was similar (18 [16-19] vs. 18 [17-19], p = 0.06). LOS was 4 [3-7] and 3 [2-6.25] days in the anemic and the non-anemic groups, respectively (p < 0.002). Multivariate analysis showed that anemia did not affect LOS (p = 0.27).
conclusionOur study suggests that preoperative anemia does not detract from the benefits of ERP after elective colorectal surgery.
