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
Boron dipyrromethene (BODIPY)-derived dyes are generally superior emitters, but their absorption and emission fail to match the bio-active optical window (650-900 nm). In this work, we explored four bisBODIPY dyes (PB1-PB4) with easy-to-go synthesis, good solubility, high photostability, and high emission quantum yield in the deep-red region. Methyl and ethyl groups were introduced in these BODIPY dyes to improve their solubility. PB4 having a fused coplanar plane was synthesized and compared to PB1-PB3 having a non-fused structure. Their geometric structure was confirmed by single-crystal analysis, and their electronic structure, along with one-photon and two-photon absorptions, was analyzed by time-dependent functional theory calculation. Their absorption/emission spectra, emission quantum yields, and lifetimes were compared. It was found that the fused coplanar structure successfully red shifted PB4 absorption/emission to the deep-red region (698/720 nm), with a quantum yield of 0.58. PB4 showed an amplified spontaneous emission effect with an output efficiency of 6.0% at a pumping power of 3000 μJ. An improved photodynamic therapy (PDT) performance was observed from PB4 via in vitro and in vivo experiments. The practical PDT performance was evaluated by cell availability. Upon a 980 nm laser radiation of 5 min, the cell viability was decreased to ∼15%.
