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

The local antiviral photodynamic inactivation (PDI) may prove to be a helpful tool reducing the viral load in the nose and throat area in the early phase of a Covid19 infection. Both the infectivity and the prognosis of SARS-CoV-2 infections in the early phase can depend on the viral load in this area. The aim of our study was to find a simplified PDI therapy option against corona viruses in this region with low dose methylene blue (MB) as photosensitizer and use of LED light instead of laser. As a substitute for SARS-CoV2 viruses we started with BCoV infected U373 cells first. We used an 810nm diode laser with 300mW/cm2 and 100J/cm
