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

Debate persists regarding the potential carcinogenicity of aspartame, as suggested by experimental studies. Therefore, we prospectively evaluated whether aspartame consumption is associated with breast cancer risk in the Nurses' Health Study (NHS) and NHS II. We used Cox models to calculate hazard ratios (HRs) and 95% confidence intervals (CIs). During nearly 30 years of follow-up, with 4 assessments of intake per year, we documented 10 814 invasive breast cancer cases. Overall, there was no association between aspartame consumption and invasive breast cancer risk (HR per 200 mg/d [approximately one 12-oz serving of diet soda] = 1.00, 95% CI = 0.98 to 1.03). We observed similar lack of associations after excluding cases occurring in the first 10 years of follow-up (n = 3125) (HR per 200 mg/d = 1.00, 95% CI = 0.97 to 1.03). In these cohorts, aspartame consumption did not increase breast cancer risk.
