The HMW1 and HMW2 Adhesins Enhance the Ability of Nontypeable Haemophilus influenzae To Colonize the Upper Respiratory Tract of Rhesus Macaques.
Article in Infection and immunity, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
Nontypeable Haemophilus influenzae (NTHi) initiates infection by colonizing the upper respiratory tract and is a common cause of localized respiratory tract disease. Previous work has established that the NTHi HMW1 and HMW2 proteins are potent adhesins that mediate efficient in vitro adherence to cultured human respiratory epithelial cells. In this study, we used a rhesus macaque model to assess the contributions of HMW1 and HMW2 to in vivo colonization. In experiments involving inoculation of individual isogenic derivatives of NTHi strain 12, the parent strain expressing both HMW1 and HMW2 and the mutant strains expressing either HMW1 or HMW2 were able to colonize more frequently than the double mutant strain lacking HMW1 and HMW2. In competition experiments, the parent strain efficiently outcompeted the double mutant lacking HMW1 and HMW2. Colonization with strains expressing HMW2 resulted in development of antibody against HMW2 in a number of the animals, demonstrating that colonization can stimulate an antibody response. In conclusion, we have established that the HMW1 and HMW2 adhesins play a major role in facilitating colonization of the upper respiratory tract of rhesus macaques, in some cases associated with stimulation of an immune response.
