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
Porcine reproductive and respiratory syndrome is an important emerging disease in India but not much is known about its prevalence and associated risk factors. The current study was conducted with the objective to estimate the PRRS sero-prevalence and identify the risk factors. A total of 6089 pig-serum samples from 27 states/union territories of India were screened for PRRS virus specific antibodies using a commercial ELISA kit. The significant risk factors and predictors were identified through multivariable logistic regression analysis. Results of the study indicates the overall seroprevalence was 17.8%. Samples from all states except Himachal Pradesh, Kerala, Madhya Pradesh, Puducherry, Punjab and Sikkim were positive. The spatial analysis indicated pockets of high seroprevalence in Nagaland and Manipur states, bordering Myanmar. The age and zone emerged as significant (
