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

In the current scenario, renewable-resource-based biomaterials offer significant advantages owing to their availability, cost-effectiveness, and non-toxic nature. This study investigated the tribological performance of Cissus quadrangularis stem fiber (CQSF)/epoxy composites with and without silica nanofillers. Composites were prepared using a fixed 30 wt% fiber content with a fiber length of 40 mm, while nano silica fillers were added at 1 wt% and 2 wt%. The friction and wear properties were evaluated using response surface methodology (RSM), and the wear mechanisms were further examined using scanning electron microscopy (SEM). The specific wear rate (SWR) ranged from 9 × 10⁻⁵ to 3.48 × 10⁻⁴ mm³/Nm, with the lowest SWR of 9 × 10⁻⁵ mm³/Nm achieved at 2 wt% nano-silica content. The coefficient of friction (COF) values varied from 0.5 to 0.85, with an optimal SWR of 9 × 10⁻⁵ mm³/Nm and a COF of 0.81. These findings highlight the potential of composites for applications requiring high roughness and low wear rates, such as gripping materials.
