The binding structure and affinity of photodamaged duplex DNA with members of the photolyase/cryptochrome family: A computational study.

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
Photolyases (PHRs) and cryptochromes (CRYs) belong to the same family known as blue-light photoreceptors. Although their amino acid sequences and corresponding structures are similar to each other, they exert different functions. PHRs function as an enzyme to repair UV-induced deoxyribonucleic acid (DNA) lesions such as a cyclobutane pyrimidine dimer (CPD) and a (6-4) photoproduct ((6-4)pp), whereas CRYs are a circadian photoreceptor in plants and animals and at the same time they control the photoperiodic induction of flowering in plants. When a new type cryptochrome was identified, it was assumed that another type of CRYs, cryptochrome-DASH (CRY-DASH), which is categorized as a subfamily of photolyase/cryptochrome family, would possess the DNA photolyase activity. However, CRY-DASH had a weak DNA photolyase activity, but the reason for this is still unclear. To clarify the reason, we performed molecular dynamics (MD) simulations for a complex of CPD-PHR or CRY-DASH with damaged double-stranded DNA (dsDNA) and estimated the binding free energy, Δ
