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

objectiveThis study aimed to investigate the associations of body mass index (BMI), television viewing time, and their combination with the risk of Type 2 diabetes among Japanese individuals using data from a large Japanese prospective cohort study.

methodsThis prospective cohort study included 23,604 Japanese participants (9,284 males and 14,320 females) aged 40-79 years. Baseline data were collected between 1988 and 1990 using a self-administered questionnaire. In the 5-year follow-up survey, Type 2 diabetes was identified through self-reported physician diagnoses. We used a logistic regression model to analyze the associations of BMI and television viewing time, and their combination with the risk of Type 2 diabetes.

resultsDuring the 5-year follow-up, 5.9% of participants developed incident Type 2 diabetes. BMI and prolonged TV viewing time were independently associated with an increased risk of developing Type 2 diabetes. Individuals with obesity (BMI ≥ 30 kg/m

conclusionsOur study underscores the importance of addressing obesity and sedentary behavior to mitigate Type 2 diabetes risk.
