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

contextSurfactant flooding represents one of the critical methods in chemical enhanced oil recovery (EOR) technology. However, under high-temperature and high-salinity conditions, the interfacial properties of surfactants are prone to alteration, leading to reduced interfacial activity. In this study, three distinct types of surfactants derived from saturated cardanol were selected: 8EO8POH (nonionic surfactant), 8EO8POC2SO

methodIn this study, Packmol was employed to construct the model, and Gromacs was used to perform molecular dynamics simulations under the GAFF force field. The simulated pressure was set to 1115.0 kPa. The temperatures were set at 303.15 K, 333.15 K, 363.15 K, 393.15 K, 423.15 K, and 453.15 K, respectively. The time step for all simulations was set to 2 fs. In the 1 ns and 15 ns NPT simulations, the Berendsen and Parrinello-Rahman methods were employed to maintain system pressure, and the temperature control was achieved through velocity-rescale. The LINCS algorithm was utilized to constrain molecular bond lengths. Short-range and long-range were used Lennard-Jones potential and Particle-Mesh Ewald (PME) summation method.
