1 · What the graph read from it

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.

2 · The registry

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

purposeLong-term totally implantable venous access ports (TIVAP) are essential for administering chemotherapy and parenteral nutrition in cancer patients. This study aimed to evaluate patient satisfaction and postoperative complications, compared to existing literature, emphasizing patient-reported outcomes (PRO) as a critical factor in treatment decisions.

methodsA prospective, monocentric observational study included 149 patients requiring TIVAP between April 13 and August 17, 2022. Patient satisfaction was assessed using a questionnaire covering four domains: overall satisfaction, willingness to choose the port again, cosmetic result, and pain experience. A meta-analysis of seven studies (1,035 patients) was performed to establish baseline data. The study assumed a non-inferiority margin of 12 points on a 0-100 scale (lower scores indicating better outcomes). Follow-ups were carried out at four weeks and six months.

resultsOf the 149 patients (mean age 58.8 years, 96% with oncological diseases), 117 (78.5%) TIVAPs were implanted via the cut-down technique, primarily using the cephalic vein (84.6%). Out of 1,240 documented catheter accesses, 91.4% were complication-free. Satisfaction scores demonstrated non-inferiority across all domains compared to literature: overall satisfaction (18.5 vs. 35.6; p < 0.001), willingness to choose the port again (15.8 vs. 29.4; p < 0.001), cosmetic result (38.0 vs. 39.9; p = 0.003), and pain experience (17.1 vs. 31.5; p < 0.001).

conclusionThe study demonstrated adequate patient satisfaction and non-inferiority of the investigated TIVAP system compared to other systems, though no superiority was found in cosmetic outcomes.
