Evaluating the efficacy of LaSota vaccination induced protection in chickens upon challenge with a genotype IV strain of Newcastle disease virus.

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
Newcastle disease (ND) is a major risk to the poultry industry which results in severe economic loss throughout the world even with vaccination. The vaccine viruses that are used in many countries include the LaSota and other live viruses that were isolated in the early and late 1950s. Reports from several laboratories including ours indicate a greater variance of the circulating strains and recent classification indicates the existence of XVIII different genotypes of NDV strains. The efficiency of the LaSota vaccination in inducing protective immunity to different heterologous strains has been a question and its efficacy upon exposure to a virulent genotype IV strain has not been reported after 1989 world-wide except for India. Serum antibody negative (SAN) chicks of either sex obtained by hatching specific-pathogen-free (SPF) eggs were vaccinated with increasing doses of the vaccine virus from 10
