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
Methotrexate (MTX) which is one of the longest-used cytostatics, belongs to the group of antimetabolites and is used for treatment in different types of cancer as well as during autoimmune diseases. MTX can act as a modulator enable to create the optimal environment to generate the specific anti-tumor immune response. A novel system for MTX delivery is its conjugation with high-molecular-weight carriers such as hydroxyethyl starch (HES), a modified amylopectin-based polymer applied in medicine as a colloidal plasma volume expander. Such modification prolongs the plasma half-life of the HES-MTX nanoconjugate and improves the distribution of the drug in the body. In the current study, we focused on evaluating the dose-dependent therapeutic efficacy of chemotherapy with HES-MTX nanoconjugate compared to the free form of MTX, and examining the time-dependent changes in the local and systemic anti-tumor immune response induced by this therapy. To confirm the higher effectiveness of HES-MTX in comparison to MTX, we analyzed its action using murine MC38 colon carcinoma and B16 F0 melanoma tumor models. It was noted that HES-MTX at a dose of 20 mg/kg b.w. was more effective in tumor growth inhibition than MTX in both tumor models. One of the main differences between the two analyzed tumor models concerned the kinetics of the appearance of the immunomodulation. In MC38 tumors, the beneficial change in the tumor microenvironment (TME) landscape, manifested by the depletion of pro-tumor immune cells, and increased influx of cells with strong anti-tumor activity was noted already 3 days after HES-MTX administration, while in B16 F0 model, these changes occurred 10 days after the start of therapy. Thus, the immunomodulatory potential of the HES-MTX nanoconjugate may be closely related to the specific immune cell composition of the TME, which combined with additional treatment such as immunotherapies, would enhance the therapeutic potential of the nanoconjugate.
