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

This study extends the application of methyl ester sulfonate (MES), a biodegradable, anionic surfactant derived from renewable resources, for chemically enhanced oil recovery (EOR) in high-salinity (up to 700 mM NaCl) and high-temperature (80 °C) conditions. MES is demonstrated to reduce oil-water interfacial tension to low values (∼0.02 mN/m at 80 °C), alter sandstone wettability to preferentially water-wet, and form stable Winsor III microemulsions. We highlight a key advancement by systematically compiling and comparing published capillary desaturation data, showing that increasing the capillary number by a factor of 10
