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
Influenza A virus (IAV) is the most widespread pathogen causing human respiratory infections. Although polymerase chain reaction (PCR)-based methods are currently the mostcommonly used tools for IAV detection, PCR is not ideal for point-of-care testing. In thisstudy, we aimed to develop a more rapid and sensitive method than PCR-based tools todetect IAV using loop-mediated isothermal amplification (LAMP) technology. We designedreverse-transcriptional (RT)-LAMP primers targeting the hemagglutinin gene. RNAs fromreference H1N1 and H3N2 showed specific RT-LAMP signals with the designed primers.We optimized the reaction conditions and developed universal reaction conditions for bothLAMP assays. Under these conditions, the detection limit was 50 copies for both RT-LAMPassays. There was no non-specific signal to 19 non-IAV respiratory viruses, such as influenza B virus, coronaviruses, and respiratory syncytial viruses. Regarding the reaction time, apositive signal was detected within 25 min after starting the reaction. In conclusion, ourRT-LAMP assay has high sensitivity and specificity for the detection of the H1 and H3 subtypes, making it suitable for point-of-care IAV testing.
