Calibration approaches for fluorescence lifetime applications using time-domain measurements.
Article in Methods in microscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This tutorial focuses on presenting experimental protocols for acquiring instrument response functions (IRF) and for calibrating the instruments using reference dyes with validated lifetime in time-domain fluorescence lifetime measurements. Step-by-step preparation of different samples used for the calibrations (scatter solutions, crystals generating second harmonic signal and reference dyes) and the corresponding instrument settings in one- and two-photon excitation are explained. The expected shape of the IRF curves and reference decays are shown using experimentally acquired examples, followed by troubleshooting of the instruments when the expected results are distorted. The discussions focus on the importance of using IRF and reference dyes for adjusting the acquisition parameters of the time-resolved instrument, for data analysis and for comparison and extrapolation of lifetime values between different biological systems.
