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
key messageCannabis trichome development progresses in distinct phases that underpin the dynamic biosynthesis of cannabinoids and terpenes. This study investigates the molecular mechanisms underlying cannabinoid and terpenoid biosynthesis in glandular trichomes of Cannabis sativa (CsGTs) throughout their development. Female Cannabis sativa c. Hindu Kush were cultivated under controlled conditions, and trichome development was analysed from week 3 to week 8 of the flowering period. We employed light microscopy, quantitative metabolomics and proteomics to analyse morphological changes in trichome secretory cell development, and temporal changes in metabolite accumulation and protein abundance. Our findings identified three distinct developmental phases: pre-secretory (T3), secretory (T6), and post-secretory (T8), the first time the three phases of trichome development have been identified and investigated in CsGTs. The pre-secretory phase was characterized by smaller secretory cells, limited metabolite accumulation and elevated levels of proteins involved in protein biosynthesis and cellular development. The secretory phase exhibited the highest biosynthetic activity, marked by larger secretory cells, increased plastidal activity, central carbon metabolism, and significant accumulation of cannabinoids and terpenoids. The post-secretory phase showed a decrease in secretory cell size, reduced metabolic activity, and a decrease in the abundance of primary and secondary metabolism enzymes, although THCA continued to accumulate. Key enzymes showed dynamic changes correlating with the stages of trichome development. This study provides a comprehensive understanding of the molecular mechanisms regulating cannabinoid and terpenoid biosynthesis in CsGTs, offering insights for enhancing the production of these valuable compounds through targeted breeding and biotechnological approaches.
