Influenza virus A (H1 and H3) and B co-circulation among patient presenting with acute respiratory tract infection in Ibadan, Nigeria.
Article in African health sciences, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundInfluenza is an acute respiratory disease that continues to cause global epidemics and pandemics in human with significant mortality and morbidity.
objectivesThis study was designed to identify the circulating influenza virus in Ibadan, Nigeria during the 2006/2007 season.
methodsThroat swab samples were collected from patients presenting with acute respiratory tract infection at the Out-Patient Departments of major hospitals in Ibadan over a period of seven months from November 2006 to May 2007. Isolation of influenza virus was performed using Madin-Darby Canine Kidney cell line and 10 days old chicken embryonated egg. Isolates was identified by haemagglutination and haemagglutination-inhibition assays using selected CDC Influenza reference antisera (A, B, subtype H1 and H3).
resultsOut of 128 patients tested, 21(16.4%) yielded positive for virus isolation. Identification of the isolates showed that 19(14.8%) were positive for influenza virus out of which 11(8.6%) and 8(6.2%) were influenza A and B viruses respectively. Influenza A virus 6(4.7%) were subtype H1; 4(3.1%) were co-subtype H1 and H3; and 1(0.8%) was not inhibited by subtype H1 and H3.
conclusionThe circulation of influenza virus A and B in this study is important to contributing knowledge and data to influenza epidemiology and surveillance in Nigeria.
