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.
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
Presently, microfluidic traps are designed mimicking the environment of hydrothermal pores, where a combination of thermophoresis and convection leads to accumulation so that high concentrations of organic matter can be reached. Such a setup is interesting in the context of the origin of life to observe accumulation and possible further synthesis of small organic molecules or prebiotic molecules such as nucleotides or RNA-fragments, but could also be used to replicate DNA-strands. The addition of coupling agents for the activation of carboxyl or phosphate groups such as 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) and EDC-hydrochloride (EDC-HCl) is necessary in order to speed up the process. This work characterizes the thermophoretic properties of EDC and EDC-HCl needed to optimize the design of the traps. At p H 4-6 spontaneous hydrolysis of EDC is observed, which also leads to a neutralisation of the p H. In order to evaluate the thermodiffusion measurements the rate constants were measured at 23 and [Formula: see text] C and the activation energy of the hydrolysis calculated.
