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
DNA fingerprinting singly or in combination with phytochemical analysis is ideal for quality control of crude plant-based drugs. However, when the source material is tannin rich stem bark, extraction of DNA by conventional methods becomes challenging. In such cases, phytochemical profiling serves as very useful tool for its identification. The work herein described a method for simultaneous DNA isolation and phytochemical extraction for downstream analysis and applications from dried bark powder of Saraca asoca and commercial samples of this crude drug as well as from those of Polyalthia longifolia, its most common adulterant. It is a modified CTAB-based method which involves a pre-extraction step by soaking samples overnight in de-ionized water followed by filtration. The residues in the filter paper were used for DNA isolation and dried filtrate was used for Reverse Phase-High-Performance Liquid Chromatography analysis. Results revealed that genomic DNA isolated was PCR amplifiable with Inter Simple Sequence Repeat and Start Codon Targeted markers. Phenolic compounds of catechin, epicatechin, and gallic acid were detected from the above dried filtrate. The method is simple, reliable and it requires small amount of sample with an option of integrating both phytochemical and DNA-based profiling, from the same starting material. Therefore, the present method could be useful for further potential applications such as quality control assessment of S. asoca products.
