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

Highly volatile persistent organic pollutants (HV-POPs) are characterized by high volatility, environmental persistence, bioaccumulative potential, toxicity, and ability for long-range transport, posing environmental and health concerns. However, research on HV-POPs remains limited, particularly in rapidly urbanizing regions, constraining understanding of their sources, environmental fate, and risks. This study investigated 52 HV-POPs, including Stockholm Convention-listed POPs like hexachlorobutadiene (HCBD) and hexa-/pentachlorobenzene (HCB/PeCB), and nonlisted HV-POPs such as volatile methylsiloxanes (VMS) and chlorinated nitrobenzenes (CNBs), using active air samplers in six major cities across Asia and Africa. The median total concentrations of HV-POPs were highest in Guangzhou (351 ng/m
