Effect of Influenza Vaccine on Prevention of Acute Attack of Chronic Airway Disease in Elderly Population.

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
This study investigated the effect of influenza vaccination on prevention of acute attacks in elderly patients with chronic airway disease and provides evidence for the prevention and control strategy of chronic airway disease in the elderly population. A total of 348 elderly patients in Linquan County, Anhui Province, China, who were also in stationary phases of chronic airway disease and were vaccinated with either the tetravalent or trivalent influenza vaccine were selected. The number of patients with acute attacks, the number of outpatients with acute attacks, the number of outpatients, the number of inpatients, the total cost of patients, the cost of outpatients, the cost of hospitalization, and the length of hospitalization were collected before vaccination and after a one-year follow-up. There was no significant difference in age and sex ratio among the two vaccination groups. The ratios of acute attacks, outpatient visits, and hospitalizations and number of outpatient visits, number of hospitalizations, total medical expenses, outpatient expenses, and hospitalization expenses were significantly higher before vaccination than those after vaccination in both the trivalent-vaccination group and tetravalent-vaccination group. Additionally, there was no significant difference in the length of stay between before and after vaccination in either the trivalent-vaccination group or tetravalent-vaccination group. The protection effect between the trivalent-vaccination group and tetravalent-vaccination group was not significant. Influenza vaccination can effectively prevent the acute attack of chronic airway disease and delay the progress of chronic airway disease.
