Expression of the OSU rotavirus outer capsid protein VP4 by an adenovirus recombinant.

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
Full-length cDNA of the VP4 gene of porcine rotavirus strain OSU was cloned into adenovirus type 5 (Ad5) downstream of the E3 promoter. The plaque-purified recombinant (Ad5-OSU VP4) expressed apparently authentic VP4 rotavirus outer capsid protein. The protein had the same molecular size (85 kDa) and electrophoretic mobility as did native OSU VP4 and was immunoprecipitated by a polyclonal antiserum raised to OSU VP4. Cotton rats that possessed prechallenge rotavirus antibodies that may have been acquired either passively or actively developed neutralizing antibodies against the OSU strain following intranasal administration of the live Ad5-OSU VP4 recombinant. The neutralizing activity was enhanced by a parenteral booster injection with baculovirus-expressed OSU VP4 antigen. In addition, a high titer of neutralizing antibodies was induced by parenteral administration of the latter antigen and subsequent intranasal administration of the Ad5-OSU VP4 recombinant. These observations indicate that the VP4 outer capsid protein of a rotavirus strain can be expressed by a recombinant adenovirus vector. This approach warrants further exploration for immunization against rotavirus disease.
