Normal Saline Push-Pause Advantage for Implanted Port Patency: A Comparative Study.
Article in Clinical journal of oncology nursing, 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
backgroundImplanted ports are essential for long-term vascular access. However, port occlusions can lead to treatment delays and reduced quality of life. Concerns about the safety of heparin have led to the exploration of safer alternatives.
objectivesThis study aimed to assess the effectiveness of 20 ml normal saline using the push-pause flush technique, compared to heparin, in preventing implanted port occlusions.
methodsA cohort study of 538 patients with implanted ports was conducted over five months. Data on demographics, port type, locking solution, occlusions, and interventions were collected. A transition from heparin-based flushing to normal saline-based flushing occurred during the study.
findingsPreliminary analysis showed low overall port occlusion rates, regardless of the locking solution used. A Fisher's exact test revealed no significant association between the type of locking solution and port occlusion. Interim findings suggest that when used with the pulsatile flush technique, normal saline may be as effective as heparin in maintaining port patency. Additional research is needed to assess the long-term implications of using saline as a locking solution.
