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.
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
At the start of 2020, a new coronavirus (COVID-19) invaded the world leading to the death of 3.92 million people. Sadly, to date, no remedy has been discovered for this virus. Preventive vaccines have been under investigation, but were unavailable until December 2020. Clinical deficiencies of nutrients may increase susceptibility to infections. This knowledge may have provided an incentive for some dietary supplement (DS) manufacturers to advertise their products as COVID-19 preventatives or cures without any substantiation, targeting mainly social media fans. The objective of this research was to assess the usage, knowledge and attitudes towards dietary supplementation before and during the COVID-19 pandemic among Lebanese people. A cross-sectional study was conducted based on a convenience sample (N = 2966) and information from participants aged 18 years and above was collected about periods before and during the pandemic. Our findings showed that attitudes towards DSs changed when the pandemic emerged and people believed that DSs can improve their health and strengthen their immunity. Despite the rise in DS prescription by healthcare professionals, the prevalence of DS use decreased from 73.3% before the pandemic to 69.9% during the pandemic (
