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
purposeThis retrospective study measured global gene abundance using RNASeq of blastocoel fluid-conditioned media from euploid ICSI-generated embryos to identify genes and signaling pathways associated with maternal age.
methodsBlastocoel fluid-conditioned media was obtained following trophectoderm biopsy of ICSI-generated day-5 blastocysts. Media for RNASeq were from 24 euploid blastocysts (9 from patients aged 35 or older). Transcriptome analysis identified differentially expressed genes when comparing media from patients of advanced maternal age to those younger than 35. Further gene abundance analysis on genes and pathways identified from the RNASeq analysis was conducted with another group of media samples using RT-qPCR.
resultsTwenty-five protein encoding genes identified in the RNASeq study were differentially expressed when comparing blastocoel fluid-conditioned media associated with patients of advanced maternal age to media associated with patients under the age of 35. Genes encoding the proteins SHARPIN and BCL2L12 showed a statistically significant increase (p < 0.05) in abundance in patients of advanced maternal age. Abundance analysis using RT-qPCR in additional media samples revealed elevated SHARPIN abundance in media associated with successful implantation in patients under 35 alongside a decrease in CASP8 abundance. This abundance pattern was the opposite in media associated with successful implantation in patients of advanced maternal age.
conclusionsThis study uncovered differential apoptotic gene abundance associated with maternal age by assessing blastocoel fluid-conditioned media from euploid blastocysts. These unique abundance patterns may provide insight into the regulation of apoptosis in embryos from women of advanced maternal age, and how this signaling pathway may impact implantation outcomes.
