Best Harvest Moment for Colon Cancer Cells From 2D Cultures for 3D Tumoroid Bioprinting: An Experimental Observational Study.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Three-dimensional tumoroids promise to enhance personalized oncology by recapitulating many features of the tumor microenvironment. In this study, human colon cells from biopsy specimens were expanded in 2D cultures and subsequently analyzed for viability, morphology, and cell counts using phase-contrast microscopy combined with FIJI ImageJ processing. Notably, survival among patient-derived cultures was variable: Patients 1 and 2 cells did not survive past Day 1; Patient 3 cells survived for nine days; Patient 4 cells, for four days; Patient 5 cells survived for 28 days - with cells seeded to a second flask (designated 5S1) on Day 9 that survived for 20 days - and Patient 6 cells survived for 17 days. Our observations indicate that only cultures with extended survival (notably Patients 5 and 6) maintain the density and morphological uniformity required for optimal bioink formulation and subsequent bioprinting of tumoroids. According to the data obtained, the best day for harvesting cells for mixing with bioink for bioprinting is the ninth day.
