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 a carcinogenicity study with SD rats exposed to pyridachlometyl (dietary dose levels, 0, 200, 2000, 10,000 and 20,000 ppm), an increase in thyroid follicular cell (TFC) adenoma and/or carcinoma was observed in male rats at ≥ 2000 ppm but not in female rats. We evaluated the mode of action (MOA) of pyridachlometyl-induced TFC tumor formation and its relevance to humans. Pyridachlometyl was neither genotoxic, cytotoxic nor immunosuppressive based on a series of toxicity studies. Data from general toxicity studies suggested that the MOA involve altered homeostasis of the hypothalamic-pituitary-thyroid (HPT) axis by hepatic uridine diphosphate glucuronosyltransferase (UGT) induction. Short-term in vivo MOA studies in SD rats showed that pyridachlometyl caused T
