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

In 2011, 68 archived beluga whale (Delphinapterus leucas) liver samples collected from Cook Inlet and the eastern Chukchi Sea from 1989 to 2006 were characterized for 12 per- and polyfluoroalkyl substances (PFAS) using targeted mass spectroscopy (MS) methods; however, at the time of the original analysis, high resolution MS (HRMS) methods were not readily available. This follow-up study utilizes both targeted as well as cutting-edge HRMS non-targeted analysis (NTA) techniques to screen for additional PFAS as well as potential contaminants of emerging concern (CECs) in the chemical space under investigation. Targeted analysis detected perfluorodecanesulfonic acid (PFDS) and perfluoroheptane sulfonic acid (PFHpS) in 10 % and 9 % of liver samples, respectively. PFDS detections were observed only in Cook Inlet whales while PFHpS was detected in whales from both locations. In addition, NTA identified four dibrominated pyrrole ring structures two with a sulfate (C
