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
Since December 2019 and the global epidemic of COVID-19 different countries have focused on vaccines, and one of the inactivated produced vaccines was the Sinopharm COVID-19 vaccine. Some side effects of this vaccine were reported previously, including pain at the vaccination site, fatigue, lethargy, headache, and tenderness, which were more prevalent among individuals <49 years old. Herein, we reported two patients aged 45 and 51 years old. Both patients have different signs and symptoms after receiving the second dose of the vaccine. None had a history of chronic disease. On examination and following labs and other diagnostic investigations, we found megaloblastic anemia due to atrophic gastritis and low intrinsic factor. These cases showed an autoimmune side effect of the Sinopharm COVID-19 vaccine that was previously reported with an exact mechanism but other features called Covid Arm, Guillain-Barré syndrome, and thrombocytopenia. The mechanism of this reaction is unclear yet.
