A Feasible Option before Cycle Cancellation for Poor Responders; STOP-START Protocol.

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
Despite the advances in controlled ovarian stimulation (COS), management of a subgroup of poor ovarian responder patients may still be challenging. We describe a feasible and simplified protocol, namely the STOP-START protocol, for poor responders defined as Patient-Oriented Strategies Encompassing Individualize D Oocyte Number (POSEIDON) groups 3 and 4, who are unresponsive to COS with maximum dose gonadotrophins. Data of 11 women unresponsive to COS were reviewed. Mean age of the patients was 36.5 ± 6.0 years. Unresponsiveness was defined as no follicular growth >9 mm and/or estradiol level less than 40 pg/ml after a week of recombinant follicle stimulating hormone (rFSH, 225-300 IU) administration. In that case, COS was stopped and each woman underwent weekly ultrasound assessment to catch a secondary follicular growth. All women showed at least one follicular growth within five to 20 days. Six women (54.5%) had spontaneous follicular growth and the other five required ovarian stimulation. At least one oocyte was retrieved from each one of seven patients (63.6%). The mean number of oocytes retrieved was 1.6 ± 1.4 and five women (45.5%) had at least one grade A embryo. Among all, two women became pregnant successfully and both gave live births (18.2%). In conclusion, STOP-START protocol may potentially be an effective, feasible, and time-saving management option for POSEIDON group 3/4 poor responders who are unresponsive to standard COS treatment with maximum dose gonadotrophins.
