Association of intrauterine platelet-rich plasma infusion before embryo transfer with endometrial response and live birth: a cohort study.

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
Background: Intrauterine platelet-rich plasma (PRP) has been proposed as an adjunctive intervention for patients with thin endometrium or recurrent implantation failure before embryo transfer, but evidence remains limited by heterogeneous protocols and small studies. Objective: To evaluate whether intrauterine PRP infusion before embryo transfer is associated with improved endometrial response and pregnancy outcomes, particularly live birth per embryo-transfer (ET) cycle. Methods: This retrospective cohort included 620 ET cycles, comprising 310 cycles exposed to intrauterine PRP before ET and 310 matched control cycles without PRP exposure. The primary outcome was live birth per ET cycle. Secondary outcomes included biochemical pregnancy, clinical pregnancy, ongoing pregnancy at 12 weeks, ectopic pregnancy, multiple pregnancy, endometrial-thickness response, triple-line endometrial pattern, conditional pregnancy progression, and delivery/neonatal outcomes. Pregnancy outcomes were analyzed using unadjusted and adjusted comparisons and multivariable models. Results: The PRP and control groups were similar in age, BMI, baseline endometrial thickness, endocrine parameters, frozen ET status, ICSI use, and single-embryo transfer. PRP-treated cycles had more prior IVF/ICSI cycles, clinician-recorded recurrent implantation failure, history of cavity-distorting fibroid, and history of hydrosalpinx. Baseline and pre-procedure endometrial thickness were similar between groups, but post-procedure endometrial thickness, ET-day endometrial thickness, and triple-line pattern were more favorable in the PRP group. In unadjusted analyses, PRP was associated with higher clinical pregnancy, ongoing pregnancy at 12 weeks, and live birth. Live birth occurred in 82/310 PRP cycles (26.5%) and 53/310 control cycles (17.1%) (risk ratio [RR], 1.55; 95% CI, 1.14-2.10; P = 0.005). After multivariable adjustment, PRP remained associated with live birth (adjusted RR, 1.55; 95% CI, 1.12-2.15; P = 0.009). Sensitivity analyses were directionally consistent. Conclusion: In this cohort study, intrauterine PRP infusion before ET was associated with improved endometrial development and higher rates of clinical pregnancy, ongoing pregnancy, and live birth.
