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

COVID-19 has been declared a global pandemic by WHO on 11 March 2020. Still, very little is known about the potential protective dietary factors for the prevention of infection and mortality due to COVID-19. Keeping in view the scarcity of literature/studies available, in this regards present study was undertaken to assess if there is any correlation between mean levels of Vitamin D in various Asia Pacific countries with the infection and mortality caused by COVID-19. We collected data for mean levels of Vitamin D for 37 Asia Pacific countries for which we have also got the data regarding the morbidity and mortality of COVID-19. The mean levels of Vitamin D were found to have a significant association with the number of cases/million(r =  - 0.394,
