Semi-Functional Quantitative Flow Cytometry Assay for Lymphocytic Choriomeningitis Virus Titration.

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
Quantitative PCR and plaque assay are powerful virological techniques used to measure the load of defective or infectious virus in mouse and human. However, these methods display limitations such as cross contamination and long run-time. Here, we describe a novel technique termed as semi-functional quantitative flow cytometry (SFQF) for the accurate estimation of the quantity of infectious lymphocytic choriomeningitis virus (LCMV). LCMV titration method using flow cytometry was previously developed but has technical shortcomings, owing to the less optimized parameters such as cell overgrowth, plate scale, and detection threshold. Therefore, we first established optimized conditions for SFQF assay using LCMV nucleoprotein (NP)-specific antibody to evaluate the threshold of the virus detection range in the plaque assay. We subsequently demonstrated that the optimization of the method increased the sensitivity of virus detection. We revealed several new advantages of SFQF assay, which overcomes some of the previously contentious points, and established an upgraded version of the previously reported flow cytometric titration assay. This method extends the detection scale to the level of single cell, allowing extension of its application for
