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

Nonlinear optical (NLO) susceptibility of Ethidium Bromide (EB) dye, an excellent NLO material, dissolved in different solvents, including ethanol, methanol, acetone, 1-propanol, DMF, and DMSO is reported. Z-scan tool is used to measure the NLO features of EB dye using open and closed aperture methods. The peak-valley transmittance graph indicating self-defocusing nonlinearity in the nonlinear refractive index of EB dye in different solvents. The nonlinear absorption coefficient showed both positive and negative nonlinearity is the result of saturable and reverse saturable absorption behavior from the open aperture curve. The absorption coefficient and nonlinear refractive index of EB dye in various solvents are found to be the order of 10
