Nanomolar Affinity Host-Dye Reporter Pairs from Fluorescently Labeled Oligoarginine Peptides and p-Sulfonatocalix[4]arene.

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
Oligoarginine peptides are of interest as cell-penetrating peptides (CPPs) and play important roles in gene regulation and immune response. Complexation of oligoarginine peptides by the supramolecular host p-sulfonatocalix[4]arene (CX4) is well-established and has led to the use of CX4 derivatives as effective counterion activators for arginine-rich CPPs and to the application of CX4 in peptide sensing. Herein, a systematic binding study between oligoarginine peptides with CX4 is reported. The results show that the binding affinity increases with increasing peptide length from ≈10
