Evaluating the Characteristics of the Totally Implantable Venous Access Device in Cancer Patients Using Fluorodeoxyglucose-PET/CT in the Absence of Suspected Catheter-Related Infections.
Article in Cureus, 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
purposeThis study evaluated the fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) imaging features associated with the totally implantable venous access device (TIVAD) in cancer patients.
methodsWe conducted a retrospective single-institution review of TIVAD placements between January 2016 and December 2020. Among these, we identified cases where FDG-PET/CT was performed to monitor malignant tumors after TIVAD placement. Increased accumulation was evaluated based on the site, TIVAD approach, and indwelling time.
resultsIn total, 145 TIVAD placements were identified in 144 patients. The median number of FDG-PET/CT examinations was two (range: 1-14). Sites of increased accumulation were found in the vein of catheter penetration (8.3%) and port (1.4%). Increased accumulations were observed only with the subclavian approach. In patients with an indwelling time > 1 month, all accumulations were observed in the vein of catheter penetration (7.9%).
conclusionIncreased FDG accumulation associated with the TIVAD is not uncommon. A small thrombus with some reactive processes at the vein penetration site may be responsible for the increased accumulation.
