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

Polytetrafluoroethylene (PTFE) and other fluoropolymers are widely used because of their exceptional chemical resistance and thermal stability. However, their disposal poses a significant environmental challenge. Conventional methods for degrading PTFE either require high temperatures or rely on complex reagents and often neglect efficient fluorine recovery. Herein, we present an approach for the room-temperature defluorination of PTFE using sodium dispersion, enabling the conversion of PTFE into sodium fluoride (NaF) under mild conditions. This method not only eliminates the need for elevated temperatures, but also demonstrates high yields of fluoride ion recovery, reaching up to 97% under optimized conditions. We further extend the application of this method to non-polymer, per- and polyfluoroalkyl substances (PFAS), including perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluorobutanesulfonic acid (PFBS) and trifluoroacetic acid (TFA), achieving similarly high yields of NaF with appropriate adjustments of the reaction time and reagent amounts.
