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
Introduction: This large multicenter study aimed to evaluate clinical outcomes using three follitropin alfa preparations within a progestin-primed ovarian stimulation (PPOS) protocol, while identifying contributing factors to cycle success. Methods: A retrospective, anonymized cohort analysis was conducted on donor-recipient cycles from 12 clinics during 2019 to 2021. 7389 oocyte donors underwent ovarian stimulation (OS) with three follitropin alfa preparations (Ovaleap Results: Whilst there were some differences in patient and stimulation characteristics, including donor age and number of retrieved oocytes, clinical variables did not significantly differ among the three study groups. Linear regression revealed donor age [0.986 (0.974-0.999)] and number of mature oocytes [1.027 (1.007-1.047)] significantly impacted ongoing pregnancy rates, while the type of follitropin alfa [1.048 (0.956-1.149)] used did not. No significant differences were observed in the cumulative live birth rate (CLBR) among oocytes obtained from stimulation with Bemfola (64.9%), Gonal-F (64.1%) and Ovaleap (66.1%), p= 0.385. Discussion: This study demonstrated comparable clinical outcomes and CLBR between biosimilars and the reference product of follitropin alfa within PPOS protocols, hence they are interchangeable in a real-world patient setting.
