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

Fluorescence Lifetime Imaging (FLI) is a technique recording the temporal decay of fluorescence emission at every pixel of an image. Analyzing the information embedded in FLI dataset requires either fitting the decay to a predefined model using nonlinear least-square fit or maximum likelihood estimation, or projecting the decay on an orthogonal basis of periodic functions as in phasor analysis. AlliGator is a Windows open source software (BSD license) implementing these approaches in a user-friendly graphical user interface (GUI) and offering numerous unique features such as Förster Resonant Energy Transfer (FRET) stoichiometry analysis, or the creation of maps of lifetime-derived quantities such as membrane potential. It leverages the unique ability of the LabVIEW graphical programming language (G) to design feature-rich GUI, and supports user-developed plugins written in python to extend its native capabilities.
