Prediction of perioperative complications in colorectal cancer
Article in World journal of gastrointestinal surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundHeart rate variability (HRV) represents efferent vagus nerve activity, which is suggested to be related to fundamental mechanisms of tumorigenesis and to be a predictor of prognosis in various cancers. Therefore, this study hypothesized that HRV monitoring could predict perioperative complication (PC) in colorectal cancer (CRC) patients.
aimTo investigate the prognostic value of HRV in hospitalized CRC patients.
methodsThe observational studies included 87 patients who underwent CRC surgical procedures under enhanced recovery after surgery programs in a first-class hospital. The HRV parameters were compared between the PC group and the non PC (NPC) group from preoperative day 1 to postoperative day (Pod) 3. In addition, inflammatory biomarkers and nutritional indicators were also analyzed.
resultsThe complication rate was 14.9%. HRV was markedly abnormal after surgery, especially in the PC group. The frequency-domain parameters (including pNN50) and time-domain parameters [including high-frequency (HF)] of HRV were significantly different between the two groups postoperatively. The pNN50 was significantly greater at Pod1 in the PC group than that in the NPC group and returned to baseline at Pod2, suggesting that patients with complications exhibited autonomic nerve dysfunction in the early postoperative period. In the PC group, HFs were also enhanced from Pod1 and were significantly higher than in the NPC group; inflammatory biomarkers were significantly elevated at Pod2 and Pod3; the levels of nutritional indicators were significantly lower at Pod1 and Pod2; and the white blood cell count was slightly elevated at Pod3.
conclusionHRV is independently associated with postoperative complications in patients with CRC. Abnormal HRV could predicted an increased risk of postoperative complications in CRC patients. Continuous HRV could be used to monitor complications in patients with CRC during the perioperative period.
