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
BACKGROUND Influenza is a viral disease causing many deaths each season. With aging, the human immune system becomes weaker, so people over the age of 65 years are at higher risk of complications after influenza infections. This population study, conducted in Poland, aimed to identify the subtypes of influenza virus infection and outcomes in individuals more than 65 years of age in the 2016/2017 to 2019/2020 epidemic seasons. MATERIAL AND METHODS The research materials were nose and throat swabs. Research was conducted in 16 Voivodship Sanitary and Epidemiological Stations and in the Department of Influenza Research, National Influenza Centre, NIPH-NIH. Methods of RNA isolation depended on the laboratory where the isolation was performed. In all laboratories, quantitative polymerase chain reaction (qRT-PCR) was used to determine the influenza virus type and subtype. RESULTS The analysis of the incidence of influenza among people over the age of 65 included the 2016/2017, 2017/2018, 2018/2019, and 2019/2020 influenza epidemic seasons. We analyzed the percentage of positive samples, the dynamics of epidemic seasons, and the percentage share of influenza viruses in the 65+ age group, according to the epidemic season and percentage of deaths. CONCLUSIONS This population study showed that, in Poland, between the 2016/2017 and 2019/2020 epidemic seasons, people who were more than 65 years of age were at higher risk of influenza virus infection and its complications. The findings support the importance of seasonal influenza vaccination in the population over age 65 years.
