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

Lubricating additives are essential for enhancing the tribological properties of grease. The development of low-cost lubricant additives with excellent biodegradability is expected to be the prevailing trend for future advancements. In this study, biodegradable ultrafine β-tricalcium phosphate (β-TCP) was utilized to enhance the friction reduction, anti-wear and extreme pressure properties of barium complex greases at high temperatures. At 150 °C and a load of 150 N, compared to the base grease, the average friction coefficient (AFC) of barium complex grease with 4.5% β-TCP was reduced by 21.82%. Meanwhile, the wear volume was reduced by 88.43%. Moreover, the extreme pressure properties of the barium complex grease were increased by 3.75 times. The lubrication mechanism of β-TCP is the formation of a protective film of P and Ca compounds on the surface of the friction partner.
