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

objectiveThis study aims to provide descriptive epidemiology of human CCHF cases in Afghanistan by demographic, geographical, and seasonal characteristics. METHODOLOGY: This paper's findings are based on the retrospective analysis of the National Surveillance System's collected data from 2016 to 2018. Weekly cases exceeding the 90th percentile of the expected number of cases were considered to be exceptional and above normal.

resultsThe National Surveillance System detected 1,284 CCHF cases from 2007 to 2018, of which 163 cases were in 2016, 245 cases in 2017 and 483 cases in 2018. A total of 891 suspected and confirmed cases were reported between 2016 and 2018, 293 (33%) of these cases were confirmed by detecting IgM antibody using ELISA and RT-PCR. Among confirmed cases, the three-year case fatality ratio (CFR) was 43.3%. Among the reported cases, 68.5% were males and 31.5% females. The frequent reported occupational groups were housewives (15%), health staff (13%), shepherds (11%), butchers (6%), students (6%), animal dealers and farmers (both 2%) respectively, 19% were unemployed, and occupation was not recorded for 26% of cases.

conclusionRecently, CCHF has significantly increased in Afghanistan. Despite the increased frequency of cases, the laboratory capacity to test specimens and overall knowledge of CCHF management remains limited.
