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

BACKGROUND/

aimUltrafine bubbles (UFBs) have been extensively researched owing to their promising physical and biological properties. However, determining the lifespan or ideal concentration of UFBs for various biological events is challenging. This study aimed to determine the maximum concentration and longest lifespan of UFBs and to verify the validity of UFBs for assessing cell properties. MATERIALS AND

methodsA generator system (HMB-H0150+P001, TOSSLEC Corporation Limited, Kyoto, Japan) generated UFBs using various gases. The size and concentration of UFBs in ultrapure water and cell culture medium were measured through a nanoparticle tracking analysis method.

resultsThe UFB concentration increased when the generator operated in a time dependent manner. The mean size of UFBs was approximately 120 nm. In the UFB lifespan, the concentration decreased by approximately 30% within the first two weeks of generation and was stable for up to 6 months. The UFB size increased by approximately 20% within the first two weeks of generation and demonstrated minor changes until the 6th month. The number of cells differed significantly with various concentrations of nitrogen gas UFBs.

conclusionThe generator system can generate UFBs with multiple concentrations within a suitable temperature. Consequently, the solution containing UFBs could be widely acceptable in cell culture systems.
