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

This study estimated the excess suicidal mortality during the COVID-19 pandemic in Japan. A Poisson regression model was used to assess the association between unemployment rates, expenditure for alcohol, eating out, and suicide, from January 2008 to March 2020. The excess suicidal mortality was assessed by applying the identified model to data from April 2020 to December 2021. The number of estimated excess deaths during COVID-19 was 3397 in men and 2390 in women. COVID-19 may have caused unprecedented psychological distress among people, owing to restricted social gatherings and prolonged uncertainties.
