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

backgroundNeurointerventional procedures rely on a variety of angiographic devices and disposables. Despite the increasing frequency of these procedures, systematic data on the scale and nature of packaging material attributable to the delivery of these neurointerventional supplies to hospitals are limited. This study aims to quantify the packaging material linked to the delivery of neurointerventional supplies, providing critical insights for future sustainable healthcare logistics.

methodsA prospective observational study was conducted over a 30-day period in April 2025. Every incoming package containing neurointerventional supplies was analyzed for weight, packaging type, and content composition. The supplies were grouped into predefined categories (eg, catheters, coils, stents). The weight of both packaging and supplies was measured, and descriptive statistical analysis was applied to summarize the data.

resultsA total of 196 packages were analyzed. The combined gross weight of all packages was 455.07 kg, with 118.31 kg (26.0%) tare weight attributed to packaging materials. Eighty-eight (44.9%) single-item deliveries were received. Catheters were the most common item, appearing in 34.2% of the packages. The median proportion of supply net weight relative to package gross weight was 57.2%. In 38.8% of packages the weight of the packaging exceeded that of the supplies. Only five packages (2.6%) contained more than two items of different types of supply categories.

conclusionThe study shows that packaging materials make a significant contribution to deliveries of neurointerventional supplies, highlighting the substantial burden of packaging waste associated with neurointerventional procedures. The findings emphasize the need for strategies aimed at reducing packaging waste to promote more sustainable practices in healthcare logistics.
