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 study aims to establish a single-time point RNA-sequencing-based endometrial receptivity test (rsERT) to provide hourly precision of endometrial WOI for patients with recurrent implantation failure (RIF).
methodsA two-phase study was conducted. In the first phase, a total of 70 patients with successful intrauterine pregnancy after personalized embryo transfer (pET) guided by three-time points rsERT were recruited for modified rsERT. Another 21 patients who underwent the prototype of single-time point rsERT were further included for optimization. In the second phase, another cohort of 574 patients with RIF that was recruited and assigned to the experimental group underwent pET guided by the modified rsERT (n = 261) or the control group underwent conventional ET (n = 313). The positive β-human chorionic gonadotropin (β-hCG), intrauterine pregnancy rate (IPR), implantation rate (IR), ongoing pregnancy rate, and live birth rate of the two groups were analyzed.
resultThe modified rsERT provided an hour-based predictive result of endometrial WOI with an average accuracy of 94.51% and sensitivity and specificity of 92.73% and 96.29%, respectively. The positive β-hCG, IPR, IR, ongoing pregnancy rate, and live birth rate of the experimental group were significantly different from those in the control group. After propensity score matching (PSM) control for the confounders, positive β-hCG, IR, and early spontaneous abortion rate showed significant differences.
conclusionThe modified rsERT provided hourly precision WOI prediction using a single-time point endometrial biopsy and pregnancy outcomes were significantly improved, providing an enhanced endometrial receptivity test as an alternative requiring only a single-time point sampling for patients with RIF.
