1 · What the graph read from it

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.

2 · The registry

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

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging tick-borne disease caused by the SFTS virus (SFTSV) of family Phenuiviridae. Since the virus was first identified in 2009, it has been rapidly spread in many Asian countries including Myanmar, Korea, Japan, and central China. In this study, we investigated the epidemiological characteristics of SFTS patients in Hefei from 2011 to 2018. In addition, we conducted a serological survey of SFTSV-specific antibody among healthy residents of five counties. We performed a retrospective observational study of SFTS cases reported to Hefei Center for Disease Control and Prevention (CDC) during Jan 2011 to Dec 2018. Almost every patient completed a structure questionnaire including clinical examination, course of disease, and history of epidemiology. A total of 754 serum specimens were collected and tested for IgG antibody with double-antigen sandwich ELISA method. Of 257 cases reported during that period, 33 died, with a case fatality rate of 13.0%. We found no significant difference between 30 non-survivors and 198 survivors except for age. The overall rate of seropositivity for SFTSV antibodies among healthy residents were 20.16%. We demonstrated that living in hilly areas, direct contact with domestic livestock and knowledge of tick-borne disease were significantly associated with positive serology result. SFTSV infection was prevalent among farming-related populations. Our study identified a relatively high seroprevalence of SFTSV-specific antibody in healthy residents, which provided the basis for asymptomatic SFTSV infections. More attention should be given to susceptible population and prevent SFTSV outbreak in high-endemic areas.
