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

Infectious diseases constitute one of the major threats to African great apes. Bonobos (Pan paniscus) may be particularly vulnerable to the transmission of infectious diseases because of their cohesive grouping and frequent social and sexual interactions between groups. Here we report two cases of a flu-like illness and possible transmission of the illness among neighboring wild bonobo groups at Wamba, DR Congo. The first flu-like outbreak started in the PE group on July 28, 2013, 2 days after they had encounters with the BI and PW groups. All PE members, except for one infant, subsequently developed flu-like symptoms, including coughing and running nose. The second flu-like outbreak occurred in the E1 group on October 14, 2013, after E1 had encountered the PE group and the two groups stayed together from October 7 to 11. Eleven out of the 15 observed party members developed symptoms over the next 4 days. The pathogens underlying the two outbreaks may have been related as two temporary immigrant females, who had previously shown symptoms while in the PE group, stayed briefly in the E1 group during the second outbreak, but did not show any symptoms.
