An Open Path to DAG: Navigating Causal Inference in Epidemiological Research.
Article in Indian journal of community medicine : official publication of Indian Association of Preventive & Social Medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Directed acyclic graphs (DAGs) are a valuable tool in epidemiology for illustrating causal relationships between variables in epidemiological research. DAGs enhance the transparency and robustness of the causal inference by delineating causal paths and identifying confounders, mediators, and colliders. It helps the researcher to identify the minimal number of variables that need to be adjusted to eliminate the effect of confounders on the causal relationships. However, this is not being widely used in epidemiological research, and when used, there is considerable variation in the way it is utilized and reported. One reason is the researchers' lack of practical knowledge on using and reporting DAGs in their studies. This article will introduce the basic concepts of DAGs to help public health researchers familiarize themselves with the various terms used in DAGs. In addition, the illustrative example provided in the article will help researchers to draw, interpret, and report DAGs in their epidemiological studies.
