Effect of methotrexate exposure at middle gestation on the inner plate of the ocular cup and lens in the rat fetus.

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
Pregnant rats were treated intraperitoneally with a single dose of methotrexate (MTX) 90 mg/kg on gestation day (GD) 13, and fetal eyeballs were examined time-dependently from GD 13.5 to 15.5. Throughout the experimental period, the inner plate of the ocular cup in the MTX group was significantly thinner than that in the control group. In the inner plate of the ocular cup on GD 15 and 15.5, whereas a developed ganglion cell layer was observed in the control group, the ganglion cell layer in the MTX group was undeveloped and indistinguishable. Disturbance of the arrangement of lens fiber cells, narrowing of the hyaloid cavity of the optic cup, and hypoplasia of optic nerve fibers were observed in the MTX group on GD 15 and 15.5. Increase of pyknosis and decrease of mitosis were induced in the optic cup and the lens epithelium of the MTX group. In the inner plate of the optic cup and the lens epithelium of the MTX group, the cleaved caspase-3- and TUNEL-positive rates increased significantly throughout the experimental period. The phospho-histone H3-positive rate in the inner plate of the optic cup decreased significantly from GD 13.5 to 14.5, and it recovered on GD 15. On the other hand, the phospho-histone H3-positive rate in the lens epithelium decreased significantly throughout the experimental period. These results suggested that optic tissue on GD 13 in rats was sensitive to MTX.
