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
purposeLung cancer is the second most common Cancer in the United States; however, it remains the leading cause of cancer-related death in the United States and worldwide. 5-fluorouracil (5-FU) is among the most administrated chemotherapeutic agents for various neoplasms. This study focused on synthesizing and characterizing P(AAm/SA)/5-Fu nanogels as a potential drug delivery system.
methodsThe nanogels were prepared by combining sodium alginate (SA) and acrylamide (AAm) monomers, followed by gamma irradiation-induced polymerization at a dose of 5 kGy. Then, the obtained nanogel was loaded with 500 ppm of 5-Fu. Transmission electron microscopy (TEM) imaging was utilized to characterize the nanogels' morphology and monodispersity with a particle size of (50 nm). Rats were randomly assigned to four groups (six animals per group): Group 1: (Control): normal healthy. Group 2: Cancer-bearing animals (animals injected with diethylnitrosamine (DEN) 20 mg/kg body weight for 3 months. Group 3: Cancer+ 5-fluorouracil (12 mg/kg body weight). Group4: Cancer+ 5-Flurouracil- Loaded P (AAm/SA) Nanogel.
resultsDEN markedly increased PTGS2, Cox2, PKB, PFKm, and ERK1 levels. Also, observed up-regulation in ALKBH5, Beclin1, ULK1, and P53 gene expressions in the cancer-bearing animal group compared with the control group. 5-fluorouracil nano gel significantly ameliorated the above-mentioned parameters and immunohistochemistry study. 5-fluorouracil nanogel significantly ameliorated the parameters mentioned above, as well as the immunohistochemistry study.
conclusionThe 5-FU-loaded P(AAm/SA) nanogel could serve as a promising approach for targeting tumor cell proliferation, speeding up autophagic processes, and overcoming chemotherapy resistance in lung carcinoma.
