To curette or not to curette; efficiency of oocyte retrieval technique.

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
purposeFollicular curetting is the gentle and rapidly rotating movement of the aspiration needle in a clockwise and counterclockwise fashion. The aim of our study is to assess this retrieval technique comparing cycle and pregnancy outcomes between curetting and non-curetting.
methodsThis was a retrospective review of 817 patients that underwent oocyte retrieval at our fertility center from January 1st, 2016 until August 31st, 2019. All patients enrolled in the study underwent standard ovarian stimulation protocols. Three physicians routinely utilized follicle curetting during oocyte retrieval, while a fourth physician did not curette. Retrievals and embryo transfers were performed based on a rotating physician schedule.
resultsRetrievals that were performed using a curetting technique had a significantly higher number of total oocytes retrieved 12.4 ± 8.1 vs 10.7 ± 7.5 (p = 0.01), and number of M2 oocytes retrieved 8.1 ± 6.4 vs 6.9 ± 6.0 (p = 0.03), resulting in an increased M2 oocyte yield 63.7% ± 41.3 vs 50.9% ± 30.6 (p = 0.0001). These patients also had a significant increase in clinical pregnancy rate per retrieval 55 vs 41% (p = 0.0016), live birth rate per retrieval 42 vs 34% (p = 0.04) and with no significant difference in multiple gestations or OHSS.
conclusionsA significant improvement in clinical pregnancy rates and live birth per retrieval was detected in patients undergoing curetting. These patients had more embryos frozen, leading to more transfers and more successful pregnancies.
