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
The cryptochrome/photolyase (CRY/PL) family is essential for life under sunlight because photolyases repair UV-damaged DNA and cryptochromes are normally part of the circadian clock that controls the activity-sleep cycle within the 24-h day. In this study, we aim to understand how the lineage and habitat of an insect affects its CRY/PL composition. To this end, we searched the large number of annotated protein sequences of 340 insect species already available in databases for CRY/PLs. Using phylogenetic tree and motif analyses, we identified four frequent CRY/PLs in insects: the photolyases 6-4 PL and CPDII PL, as well as the mammalian-type cryptochrome (MCRY) and Drosophila-type cryptochrome (DCRY). Assignment of CRY/PLs to the corresponding insects confirmed that light-exposed insects tend to have more CRY/PLs than insects with little light exposure. Nevertheless, even insects with greatly reduced CRY/PLs still possess MCRY, which can be regarded as the major insect cryptochrome. Only flies of the genus Schizophora, which includes Drosophila melanogaster, lost MCRY. Moreover, we found that MCRY and CPDII PL as well as DCRY and 6-4 PL occur very frequently together, suggesting an interaction between the two pairs.
