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

Sanitary napkins are essential during menstruation, but they can sometimes cause skin irritation due to friction. In this study, we propose a novel design: introducing a low-friction layer within the bulk of a sanitary napkin. Friction tests were conducted between an artificial skin block and sanitary napkin specimens with and without a low-friction layer. The strain distribution on the lateral side of the artificial skin block was experimentally measured. The friction coefficient and strain decreased when the low-friction layer was applied under loads greater than 1.96 N. The strain increased with normal load. Because lower strain on the skin correlates with reduced skin irritation, the use of a low-friction layer in sanitary napkins is expected to reduce skin irritation, particularly under high contact pressure.
