Effect of polyhexamethylene biguanide-coated central venous catheters on bacterial colonization in cancer patients undergoing abdominal surgery: a randomized controlled trial.

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
Background: Central venous catheters (CVCs) are widely used in critically ill patients, including cancer patients, but are associated with complications such as catheter-related bloodstream infections (CRBSIs). This study evaluates the effectiveness of polyhexamethylene biguanide (PHMB)-coated CVCs in reducing catheter-tip bacterial colonization in cancer patients undergoing abdominal surgery. Methods: A prospective, randomized, monocentric clinical trial was conducted at Peking University Cancer Hospital from March 2017 to April 2019. Surgical cancer patients requiring CVCs were randomized into two groups: a PHMB-coated CVC group (Certofix Results: A total of 1,185 patients were included in the analysis. The incidence of catheter tip bacterial colonization was 2.5% in the PHMB-coated group and 4.2% in the standard CVC group ( Conclusion: Polyhexamethylene biguanide-coated CVCs did not significantly reduce catheter tip bacterial colonization in the overall population but showed a beneficial effect in male cancer patients undergoing abdominal surgery. In clinical practice, it is necessary to consider various factors when selecting the type of catheter. Clinical trial registration: No. chiCTR-IPR-16010027.
