The effect of rLH supplementation to the GnRH-antagonist protocol on endocrine dynamics in the advanced reproductive age.
Trial report in Journal of endocrinological investigation, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
purposeTo explore serum endocrine dynamics, specifically LH levels, following rLH supplementation to rFSH following GnRH-antagonist treatment in the advance reproductive age.
methodsWomen were prospectively and similarly treated employing rFSH and the flexible GnRH-antagonist protocol, while rLH was supplemented only to the study group. Serum FSH, LH, E
resultsWhile serum LH drop were similar before GnRH-antagonist stimulation, it dropped more times in the control group compared to the study group. Among women receiving rFSH only, serum LH levels dropped ≤2, ≤1 and ≤0.5 mIU/mL in 71.4, 46.4, and 28.6% of cases, while this occurred only in 38.7% (P = 0.01), 6.5% (P = 0.0004) and 3.2% (P = 0.007) of women receiving combined rFSH and rLH treatment, respectively. The same trend was found when serum LH dropped in at least two occasions following the GnRH-antagonist administration. Conversely, serum LH diagrams throughout the follicular phase did not differ between the two groups. Furthermore, individual area under the curve values of LH, E
conclusionsDifferent strategies to explore LH dynamics following the GnRH-antagonist administration have resulted in diverse results, implying the need for a consensus definition of LH threshold for adequate folliculogenesis and steroidogenesis. Such action would pave the way for understanding which groups of patients may benefit from rLH supplementation.
