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

Although medicines are less toxic than other toxicants, increased production and usage of pharmaceuticals have led to many concerns regarding their toxic effects on human and non-target organisms. Additionally, reproductive toxicity after long-term exposure is difficult to anticipate. Tamoxifen (TAM), a selective estrogen receptor modulator, has been widely used as an anticancer drug for mammalian breast and endometrial cancers. With increased TAM usage, it has frequently been reported that TAM is a potential endocrine disruptor capable of interfering with reproduction in non-target organisms. However, the mode of action of TAM in the endocrine system is unknown. In this study, we performed a 21-day chronic toxicity test using the crustacean Daphnia magna and investigated the transcriptional modulation of major genes related to the endocrine system, molting, development, and reproduction (i.e., Dm-vtg2, vmo1, cyp314, usp, and ecrb) after TAM exposure for 3, 6, 12, and 24 h. Our results showed a concentration-dependent decrease in the total number of offspring per individual, except for the concentration 25 μg/L; additionally, the expression of oogenesis-related genes was induced early but was later inhibited by TAM exposure. Additionally, molting-related genes were also downregulated in a time-dependent manner. Our findings suggested that TAM regulates reproduction by interfering with the molecular mechanisms involved in oogenesis and molting. This study supports the hypothesis that D. magna are a useful model to rapidly evaluate the reproductive effects of pharmaceuticals.
