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
Light-harvesting complexes (LHCs) play essential roles in light capture and photoprotection. Although the functional diversity of individual LHCs in many plants has been well described, knowledge regarding the extent of this family in the majority of green algal groups is still limited. In this study, two different LhcSR genes, LhcSR1 and LhcSR2 from Chlamydomonas sp. ICE-L, were cloned from the total cDNA and characterized in response to high light (HL), low light (LL), UV-B radiation and high salinity. The lower F (v)/F (m) as well as the associated induction of non-photochemical quenching (NPQ), observed under those conditions, indicated that Chlamydomonas sp. ICE-L was under stress. Under HL stress, the expression of LhcSR1 and LhcSR2 increased rapidly from 0.5 h HL and reached a maximum after 3 h. In LL, LhcSR2 expression was up-regulated during the first 0.5 h after which it decreased, while the expression of LhcSR1 decreased gradually from the beginning of the experiment. In addition, the transcript levels of LhcSR1 and LhcSR2 increased under UV-B radiation and high salinity. These results showed that both genes were inducible and up-regulated under stress conditions. A higher NPQ was accompanied by the up-regulated LhcSR genes, suggesting that LhcSR plays a role in thermal energy dissipation. Overall, the results presented here suggest that LhcSR1 and LhcSR2 play a primary role in photoprotection in Chlamydomonas sp. ICE-L under stress conditions and provide an important basis for investigation of the adaptation mechanism of LhcSR in Antarctic green algae.
