Oocyte Quality and Blastocyst Formation Rate with Dual Stimulation in Patients Belonging to POSEIDON Groups 3 and 4: A Retrospective Comparative 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
Aim: To evaluate the oocyte retrieval rate and blastocyst formation rate with DuoStim protocol in patients belonging to POSEIDON groups 3 and 4. Methods: This observational, retrospective, single-center study including 90 patients belonging to POSEIDON groups 3 and 4 was conducted at a tertiary care hospital from October 2017 to March 2020. Patients were allocated into two groups based on POSEIDON classification criteria: group A (POSEIDON group 3) and group B (POSEIDON group 4). DuoStim protocol was performed with human menopausal gonadotropin (hMG) at 225 IU and 300 IU in groups A and B, respectively. Study groups were again subdivided by considering the phase in which stimulation had been done [follicular phase stimulation (FPS) and luteal phase stimulation (LPS)], and then, inference was made accordingly in terms of oocytes retrieval rate and blastocysts formation rate. Data were compiled and analyzed using statistical software SPSS version 20. Results: The baseline characteristics of two groups were compatible with POSEIDON groups 3 and 4. A significant difference was found between study groups with respect to age and anti-mullerian hormone levels ( Conclusion: In patients belonging to POSEIDON groups 3 and 4, the number of oocytes retrieved and blastocyst formation rate were greater in LPS stage when compared to FPS with DuoStim protocol.
