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

backgroundIn 2019, the EAT-Lancet commission defined a "planetary health diet", a combination of food groups and ranges of food intakes that would simultaneously optimize human health and environmental sustainability. We aimed to evaluate adherence to the Planetary Health Diet Index (PHDI) and breast cancer incidence.

methodsWe followed 68,254 participants in the Nurses' Health Study (NHS; 1986-2018) and 93,283 in the Nurses' Health Study II (NHSII; 1991-2019). The PHDI was calculated every 4 y using a validated, semiquantitative food frequency questionnaire. Hazard ratios (HRs) were calculated using multivariable proportional-hazards models.

resultsDuring 4,182,897 person-years of follow-up, we documented 10,378 invasive breast cancer cases. Women in the highest, compared to lowest, PHDI quintile (Q) were at lower breast cancer risk (HR

conclusionsAdhering to a diet that supports both human and planetary health was associated with lower breast cancer risk, particularly ER-negative tumors. Strategies to reduce breast cancer incidence should emphasize the win-win opportunities for a high planetary health diet.
