1 · What the graph read from it

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.

2 · The registry

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

Human respiratory syncytial virus (RSV) causes acute respiratory illness, attributing to deaths among young children and older adults worldwide. RSV neutralization assay is an important tool to measure RSV neutralization antibody that can prevent infection and severe complication of RSV. Conventional RSV neutralization assays have some limitations of speed and cost, especially for expensive kits, reagents or instruments required for detection. To solve this problem, this paper describes an improved simple and economical RSV neutralization assay protocol using recombinant RSV (rRSV) expressing reporter fluorescent protein to measure RSV growth as reporter activity with plate reader. The condition of 3 days culture demonstrated sufficient fluorescent activity even when small amounts of rRSV were used to inoculate Hep-2 cells. In addition, white 96-well cell culture plate showed better stable reporter activities than black plate. Furthermore, RSV neutralization assay protocol using rRSV-reporter fluorescent protein demonstrated similar signal detection capacity for RSV antibody titer detection compared to other protocols, such as rRSV-Luciferase and ELISA assay. The new RSV neutralization assay protocol can be applied to RSV antibody titration of numerous samples necessary for RSV surveillance or antiviral testing.
