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 combination of two photochromic molecules into a multimodal photoswitch offers the potential to generate new properties related to molecular solar thermal (MOST) systems. A system can only be considered suitable for MOST applications if it meets key criteria, including a high quantum yield and an extended half-life of the high-energy isomer. Achieving this combination remains a significant challenge. In this study, we present the coupling of an azobenzene unit (AZO) with a norbornadiene system (NBD) via ester functions to develop new bi- and trimodal AZO-NBD photoswitches that exhibit synergistic effects. Photochemical studies reveal that both the NBD and AZO components of the hybrid are switchable. In one case, all isomer types could be selectively produced. Furthermore, each metastable unit can be switched back independently to its corresponding thermodynamically stable form. The quantum yields and half-lives for the NBD and AZO components of the hybrid system could be determined separately. The integration of AZOs has demonstrated the potential to extend the half-lives of NBDs to up to 122 days in certain cases, as confirmed through comparative analysis with reference systems. The enhanced rate of back-conversion was further facilitated by the presence of TFA as a catalyst.
