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

Nanoplastics (NPs) pose escalating environmental risks owing to their high mobility in porous media, yet the influence of abundant iron oxide-natural organic matter (NOM) complexes on the transport of pristine and UV-aged NPs remains poorly understood. This study investigated how ferrihydrite-humic acid (Fh-HA) coprecipitates affect the migration of different-sized and aged polystyrene NPs (PS NPs) using quartz sand (QS) column experiments under varying solution chemistry conditions. At 1 mM NaCl and pH 5.5, Fh-HA coprecipitation enhanced NP transport compared to a single Fh coating, improving transport efficiency by 25.5%. Raising pH to 9.5 restored NP transport efficiency in QS-Fh (83.4%) and QS-Fh-HA (86.1%). Under 10 mM Ca
