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

A sensitizer is a vital component of dye-sensitized solar cells (DSSCs); it absorbs incident photons, excites electrons, and facilitates charge transfer to the semiconductor. In the present work, modification of betalain dyes through grafting of electron donor groups has been performed. The reported optoelectronic properties of the investigated dyes are determined using density functional theory (DFT) and time-dependent DFT methods. The investigated sensitizers exhibit maximum absorption between 400 and 442 nm with light-harvesting efficiencies exceeding 93%. Favorable interactions are observed between the dyes and the hydrogenated TiO
