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
aimTo evaluate the spatiotemporal expression pattern of PPARγ in embryonic and early postnatal stages of rat retina.
methodsFetal rats were collected at 13-18d of gestation (GD) from pregnant females and postnatal rats at 1d (P1) and 5d (P5) after birth were also used. We used RT-PCR to detect PPARγ mRNA and immunohistochemical to observe PPARγ protein. And at last, we chose HE staining showed the structural changes of rat retina during development.
resultsRT-PCR analysis showed that PPARγ mRNA was expressed as early as GD13 and gradually decreased as maturation continued. However, the PPARγ gene expression significantly increased after birth, especially in P5. Immunohistochemical analysis showed PPARγ protein was expressed throughout the retinal neuroepithelium at GD13 and GD14, and then decreased during late embryogenesis but remained relatively high in the predicted ganglion cell zone. During postnatal development, PPARγ protein was remarkably increased and the positive signals were mainly located in nerve fiber layer (NFL), ganglion cell layer (GCL) and outer layers of the retina.
conclusionThe spatiotemporal changes of PPARγ expression demonstrated that PPARγ might play a role in regulating the differentiation and maturation of retinal cells.
