Progesterone levels predict pregnancy outcomes in individuals with fallopian tube associated infertility.

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
backgroundThis study aimed at determining the predictive value of human chorionic gonadotropin and progesterone levels on pregnancy outcomes in patients receiving in vitro fertilization due to fallopian tube associated infertility.
methodsWe retrospectively analyzed the clinical data of 854 cycles due to fallopian tube associated infertility in vitro fertilization fresh embryo transfer. The clinical data had been collected from January 2010 to December 2018 and was divided into 7 groups depending on the progesterone level on human chorionic gonadotropin administration day. Live birth rates and observation trends were calculated. The receiver operating characteristic curve was established to determine the optimal cutoff value for progesterone, which was used to further divide the data into 3 groups; Group 1 (progesterone ≦ 1.0 ng/ml), Group 2 (1.0 ng/ml ≤ progesterone ≤ 1.25 ng/ml), and Group 3 (progesterone ≥ 1.25 ng/ml). We then compared the ovulation results and clinical outcomes among the 3 groups.
resultsThere were no significant differences in age, infertility years, gonadotropin dosage, gonadotropin days, Luteinizing hormone level on human chorionic gonadotropin day, 2 pronuclear fertilization rates, clinical pregnancy rates, live birth rates, full-term birth rate, and preterm birth rates among the three groups. However body mass index (p = 0.001), basal luteinizing hormone (p = 0.034), estrogen peak (p < 0.001), number of oocytes obtained (P < 0.001) were significantly different.
conclusionsProgesterone level on human chorionic gonadotropin day does not affect the clinical pregnancy rate and live birth rates after in vitro fertilization. However, progesterone levels between 1.0 and 1.25 ng/ml may lead to good clinical pregnancy outcomes.
