Long-term adaptation of the Bombyx mori BmN4 cell line to grow in serum-free culture.
Article in In vitro cellular & developmental biology. Animal, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Bombyx mori ovary-derived BmN4 cells have been successfully adapted to a commercial serum-free medium (SFM; SF900-II) by gradually reducing the serum-containing TC-100 medium content from 100 to 0% (v/v). The BmN4 cells adapted to the SFM (BmN-SFM) adhered strongly to the culture flask and showed altered cell morphology. The BmN-SFM was subcultured 200 times, and the population doubling time was 4.70 d. Infection studies showed that BmN-SFM cells were easily susceptible to B. mori nucleopolyhedrovirus (BmNPV), and both the multiplication of budded virus and the promoter activity of the polyhedrin gene in BmN-SFM cells were almost the same as those in BmN4 cells before adaptation. Additionally, mouse interleukin-3 expressed by a recombinant BmNPV was normally secreted and modified with N-linked glycans in BmN-SFM cells. These findings indicate that BmN-SFM is particularly useful for a BmNPV-based baculovirus expression vector system with serum-free conditions.
