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
Advancing biomedical studies necessitates the development of cutting-edge technologies for the rapid extraction of nucleic acid. We characterized an RNA capture pin (RCP) tool that is non-destructive to the sample and enables rapid purification and enrichment of mRNA for subsequent genetic analysis. At the core of this technology is a pin (200 µm × 3 cm) functionalized with dT15 capture sequences that hybridize to mRNA within 2 min of insertion in the specimen. Two methods for immobilizing the oligos on the surface of the RCPs were investigated: gold-thiol and biotin-streptavidin. The RNA capture efficiency of the RCPs was assessed using a radish plant. The average reverse transcription-quantitative polymerase chain reaction (RT-qPCR) cycle amplification values were 19.93 and 24.84 for gold- and streptavidin-coated pins, respectively. The amount of RNA present on the surface of the probes was measured using the Agilent 2100 Bioanalyzer. RNA sequencing was performed to determine the mRNA selectivity of the RNA capture pin. Gene read count analysis confirmed that the RNA purified via the gold-plated RCPs contained 70% messenger RNA, 10% ribosomal RNA, and 20% non-coding RNA. The long-term stability of the bond between the dT15 oligos and the surface of the RCPs was assessed over 4 months. A significant decrease in the dT15 surface coverage of the streptavidin-coated RCPs was observed after 2 weeks of storage at 4 °C. The gold-thiol RNA capture pins exhibited a retention rate of 40% of the oligos after 4 months of storage.
