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
SARS-CoV-2 and Influenza viruses are both highly transmissible airborne viruses and causing high morbidity and mortality. Co-infection of these two viruses results in severe disease that have been observed when influenza and SARS-CoV-2 viruses cocirculated in the past three years, and vaccination is still the effective way to prevent these two diseases. However, influenza and COVID-19 vaccines are designed and manufactured in different platforms, all the individuals will need to get two shots in order to prevent those two severe respiratory diseases. Therefore, it is urgent to develop a Flu-COVID combo vaccine to provide an efficient way for receiving immunization against those two diseases. In this study, we developed a flu-COVID combo vaccine that includes both influenza virus haemagglutinin (HA) proteins and SARS-CoV-2 Spike (S) protein which formulated with AddaVax. K18-hACE-2 transgenic mice were intramuscularly vaccinated with either combo vaccine or mono Flu (HA) or COVID (S) recombinant protein vaccine in a prime-boost-boost regimen, and then were challenged with lethal doses of influenza virus or SARS-CoV-2 to evaluate vaccine efficacy. The results showed that Flu-COVID combo vaccine protected mice from both Influenza and SARS-CoV-2 challenge by preventing body weight loss and clinical signs progression. The protective immune responses elicited by Flu-COVID combo vaccine were equivalent to those elicited by mono flu or COVID recombinant protein vaccines. In conclusion, our study highlights the effectiveness of the FLU-COVID combo recombinant protein vaccine in preventing both influenza and COVID-19 infections.
