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
Holotrichia parallela is an important agricultural underground insect pest and also an edible and medicinal insect. Establishing a new cell line of H. parallela will provide a rapid and convenient tool for the studies on its physiology, pathology, and gene functions. In this study, by using the embryonic tissue of H. parallela as the material, we established a new cell line named Hp-E-1. The microscopic observation of its morphological characteristics revealed that its cellular morphology was mainly in the spherical morphology with a mean cellular diameter of 17.71 ± 2.34 μm, accounting for 67% of the total cells. The spindle-shaped cells accounted for 33% of the total cells with a mean size of 23.51 ± 4.37 × 13.98 ± 2.05 μm. The chromosomal number varied from 7 to 40, with about 50% of the cells having a diploid chromosome number of 2n = 20. Random amplified polymorphic DNA (RAPD) analysis indicated that the profiles of PCR-amplified fragments of this cell line were basically similar to those of the embryonic tissues of H. parallela but were obviously different from those of cell line BTI-Tn5B1-4 of Trichoplusia ni and cell line Sf-9 of Spodoptera frugiperda. The DNA fragment encoding mitochondrial cytochrome C oxidase subunit I (COI) gene of this cell line shared 99.7% homology with that of the embryonic tissue of H. parallela, confirming that this cell line is indeed derived from H. parallela. The results of growth curve measurement indicated that the population doubling time of this cell line was 136.7 h. Cell line Hp-E-1 could not be infected by three viruses Autographa californica multiple nucleopolyhedrovirus (AcMNPV), Bombyx mori nucleopolyhedrovirus (BmNPV), and Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV).
