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
In the recently expanding global cultured meat market, fetal bovine serum (FBS) substitutes are being designed as one of the solutions to the ethical issues of FBS and the industrialization of cultured meat. This study aims to select the optimal FBS substitute by comparing the culture efficiency of skeletal muscle satellite cells (SMSCs) according to the method of producing substitutes using eggs. SMSCs cultured under low-serum conditions with whole egg extract as an FBS substitute exhibited a cell proficiency similar to those in media containing commercial FBS, and it was shown that up to 75% of commercial FBS could be replaced. The production method of this substitute was improved compared to the previously announced production method of an FBS substitute derived from egg white, shortening the production time by approximately 53% and increasing the protein yield by up to 5.79 times. Based on this, when 10% chicken serum and improved substitutes derived from whole eggs (E5H) were mixed, it was possible to replace 100% of commercial FBS, and myotubes could be produced with similar differentiation efficiency. Therefore, when E5H is applied to the medium, the cell culture cost is expected to be 2.91 times lower than that using commercial FBS, and when mixed with chicken serum, SMSCs can be cultured at a savings cost of up to 8.10 times. In conclusion, this study improved the proliferation efficiency of three SMSC types using egg-derived FBS substitutes and is expected to effectively reduce the production cost of cultured meat.
