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

backgroundThree studies have suggested a potential positive association between the use of tamoxifen in breast cancer and Parkinsonism, mainly after long-term exposure.

objectivesTo explore this potential signal, we performed a case/non-case study using the World Health Organization Global Individual Case Safety Reports (ICSRs) database, VigiBase® between 1979 and 2018.

methodsAmong women ≥ 55 years, we measured the risk of reporting "Parkinsonism" compared with all other adverse drug reactions [as a reporting odds ratio (ROR 95% CI)] for tamoxifen compared to all other drugs or aromatase inhibitors.

resultsDuring the study period, 356 ICSRs of Parkinsonism reported with tamoxifen were identified. We failed to find a positive association between tamoxifen exposure and Parkinsonism in comparison with exposure to other drugs (ROR = 0.79; 95% CI 0.71-0.88) or aromatase inhibitors (ROR = 0.39; 95% CI 0.33-0.46).

conclusionThis study did not find evidence for Parkinsonism associated with tamoxifen.
