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 notifiable and highly contagious disease causing a significant economic loss in village chicken production. So, a cross-sectional study was conducted in the East Gojjam zone of Ethiopia to determine the status of ND among unvaccinated village chickens. The study sites were selected randomly. However, the chicken owners included were households that had at least four chickens with no prior history of ND vaccination. A total of 314 serum and 76 pooled tracheal and cloacal swab samples were collected from apparently healthy birds. The hemagglutination inhibition (HI) test and reverse-transcription polymerase chain reaction (RT-PCR) were conducted for serological and virological tests, respectively. The data were analyzed using the SPSS version 20 software package. Descriptive statistics and generalized linear mixed models were used for data analysis. The overall seroprevalence rate at the individual chicken level was found to be 93% (292/314 chickens). At the household level, ND was identified in all sampled households, with a minimum of two seropositive chickens found in each household. However, these chickens tested negative for the ND virus by RT-PCR. The seroprevalence rates of the NDV at each study site were 95.0%, 96.0%, and 86.9% for Gozamin, Enemay, and Debre Elias woredas, respectively, with a statistically significant difference (
