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

Packing conformations of molecular aggregates are known to strongly influence the locations and intensities of spectral peaks. Here, we develop the third-order nonlinear spectroscopy signals for a purely electronic model of a molecular dimer, which is a prototype aggregate system. The model-which focuses on excited-state absorption (ESA) pathways in two-dimensional electronic spectra-reveals that orientational averaging leads to diagnostic ESA peak locations for H- and J-dimers. We constructed DNA-templated dimers of cyanine molecules as representative systems and used ultrabroadband two-dimensional electronic spectroscopy measurements to support the predicted signatures arising from the theoretical model. Fitting of steady-state spectra supports the assigned packing conformations. The results elucidate how ESA peaks can be diagnostic spectral signatures of packing conformation. This work lays the foundation for future studies that can include the complicating effects of vibronic states and additional electronic levels.
