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

Introduction: Suicide remains a major public health concern in Japan. Age-period-cohort analysis can differentiate the effects of age, date, and birthyear on an outcome. This study used an age-period-cohort analysis to analyze suicide mortality in all of Japan and in the 47 prefectures. Methods: Suicide mortality data from 1980 to 2021 were from the Global Burden of Disease database. Trends in the crude and age-standardized mortality rate were analyzed using Joinpoint regression. Age-period-cohort analysis was conducted using a Poisson model. Results: The suicide rate was consistently greater in men than in women. Analysis of different age groups indicated the highest rate was in men aged >80 years, although it decreased in this group over time. The suicide rate increased in the group aged 15 to 19 years, particularly in cohorts born after 1972. A strong period effect occurred from the late 1990s to early 2000s, particularly among working-age men in their 50s and 60s. There were some disparities among prefectures, in that Akita had the highest rate and Tokyo had the lowest. Conclusions: We identified key age-period-cohort effects of suicide in Japan. Economic downturns and generational differences affected suicide risk, and adolescents and middle-aged men had high risk.
