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 microscopy (FLIM) measures the average time that a fluorophore spends in the excited state. FLIM is exceptionally useful as an imaging tool because the lifetime of a fluorophore is independent of its excitation and emission profiles. As such, even spectrally identical fluorophores can often be distinguished on the basis of their fluorescence lifetimes. Furthermore, given the dependence of fluorescence lifetime on the relative magnitude of radiative and nonradiative decay rates, it is possible to both predict and modulate the lifetime of a single fluorophore for applications in FLIM multiplexing. Herein, we provide an overview of the protocols necessary for transfection-free FLIM multiplexing in live cells. Protocols are provided for the in vitro reactions required to initially screen bioorthogonal handles and dyes, incubation of the small molecule probes required for FLIM multiplexing with live mammalian cells, and the setup of FLIM experiments. We also provide a discussion of methods available to analyze FLIM data to extract lifetime data.
