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
S-palmitoylation, a reversible lipid-based post-translational modification, is notably elevated in colorectal cancer (CRC) due to common lipid metabolism disorders. It has been reported to play crucial roles in regulating membrane composition, cell proliferation, and metastasis in various malignancies such as pancreatic and breast cancers. However, its role in the progression of CRC remains poorly understood. ZDHHC9, a member of the palmitoyl transferase family, is significantly upregulated in CRC patients and correlates with poor prognosis. Knockdown of ZDHHC9 impairs CRC cell proliferation and migration both in vitro and in vivo. RNA sequencing revealed that ZDHHC9 depletion markedly downregulates the cAMP signaling pathway. Mechanistically, ZDHHC9 knockdown impairs ADCY4 activity by reducing S-palmitoylation of KLF5 at cysteine 438, thereby modulating the ZDHHC9/KLF5/ADCY4 axis and downstream cAMP/PKA/CREB signaling to influence CRC cell proliferation and migration. Our findings demonstrate that ZDHHC9 promotes CRC progression by regulating intracellular cAMP levels through KLF5 palmitoylation, providing a novel therapeutic perspective targeting palmitoylation in CRC. The mechanism diagram of this study. ZDHHC9 mediates palmitoylation of KLF5 at cysteine 438, thereby enhancing ADCY4 activity and increasing intracellular cAMP levels. This elevation in cAMP promotes PKA and phosphorylation of CREB, ultimately activating the cAMP/PKA/CREB signaling pathway, which contributes to the regulation of CRC cell proliferation, migration, and resistance to 5-FU.
