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

This study presents the third-order nonlinear optical (NLO) properties of a natural dye derived from lawsonia Inermis, investigated using Z-scan with continuous-wave He-Ne laser at a wavelength of 632.8 nm. The natural dye exhibited self-defocusing nonlinear refractive index and reverse saturable absorption (RSA) based nonlinear absorption coefficient. The self-defocusing behavior arises from thermal nonlinearity, while the RSA effect is attributed to a higher excited-state absorption cross-section compared to the ground state. The nonlinear refractive index and nonlinear absorption coefficient of the natural dye are determined to be on the order of 10
