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 recent research on regenerative medicine, three-dimensional (3D) tissue reconstruction using the induced pluripotent stem cell (iPS cell) differentiated cells has attracted attention. In this study, mouse lungs at 1.5, 10, and 20 d old were subjected to enzyme treatment, and aggregates formed in serum-free suspension culture (3D-culture) were observed. The number of aggregates formed was the highest in 1.5 d. The cell aggregates in which the interior of the aggregate is filled and form small vacuoles and the organoid-like aggregates having a relatively large vacuole inside and forming the alveolar-like structure were observed. At 1.5 d, the formation ratio of the organoid-like aggregates was the highest and aggregate size was small at 20 d. For the cell aggregates derived from 1.5 d, positive cells of SSEA-1, CD29, CD90, CD105, alveolar epithelial stem cell marker of SP-C, and Sca-1 were observed in the center. In the cell aggregates derived from 10 d, the expression level of 1.5 d each protein markers and OCT4 gene of transcription factor was decreased, and furthermore, markers were hardly observed in the organoid-like aggregates derived from 10 d. In addition, cells surrounding the vacuole of organoid-like aggregate obtained over 10 d differentiated into periodic acid-Schiff (PAS), podoplanin-positive cells. When the formed cell aggregates were dispersed, cell aggregates and organoid-like aggregates were reformed. Comparing 3D-culture and adhesion culture (2D-culture), SP-C expression of 10 d of cells was maintained. Expression of markers of undifferentiated markers and alveolar tissue stem cells decreased when cell aggregates were cultured with the addition of fetal bovine serum.
