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

backgroundDietary intake of isoflavones has been positively associated with risk of breast cancer (BC) in some earlier studies. In addition, most studies on diet-disease associations came from western countries and limited data are available in the Middle-East.

methodsThis case-control study was performed on 350 women with BC aged over 30 years who were recruited from hospitals or private clinics in Isfahan, Iran. All patients were diagnosed with BC during the maximum of the last 6 months using physical examination and mammography findings. Using cluster method sampling, 700 apparently healthy age- and socioeconomic status-matched controls were randomly selected from healthy women who had no relationship with BC patients and had no familial history of BC. Data on dietary intakes were collected using a validated food-frequency questionnaire. The DPI was calculated based on dietary energy derived from foods rich in phytochemicals (kcal) divided by total daily energy intake (kcal) of each participant.

resultsMean ± SD age and BMI in the study participants were 62.4 ± 10.8 years and 24.3 ± 5.2 kg/m

conclusionIn conclusion, a protective association was observed between DPI and BC in this case-control study. Therefore, high consumption of foods rich in phytochemicals such as fruits, vegetables, and whole grains might help reducing the odds of BC among women.
