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

backgroundUse of alternative medications and herbal remedies is widespread in the United States and across the globe. These traditional medications can be contaminated with toxic metals. Despite several case reports of poisoning from such contamination, the epidemiological data are still limited.

objectivesTo report on a cluster of lead and mercury toxicity cases in 2011 among a community of adherents of traditional medical practice of Ayurveda.

methodsAdherents of Ayurveda were offered heavy metals screening following the identification of the index case.

resultsForty-six of 115 participants (40%) had elevated blood lead levels (BLLs) of 10 μg/dl or above, with 9.6% of BLLs at or above 50 μg/dl.

conclusionsThis is the largest cluster of lead and mercury toxicity following use of Ayurvedic supplements described in the literature in the US. Contamination of herbal products is a public health issue of global significance. There are few regulations addressing contamination of "natural" products or supplements.
