Efficiency of mild ovarian stimulation with letrozole co-treatment in expected low ovarian responders.
Observational study in JBRA assisted reproduction, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveOvarian stimulation (OS) is a critical step in assisted reproductive techniques (ART); it has been routinely adopted since it substantially increases the whole process efficiency. Our study aims to compare the efficiency of mild OS with letrozole co-treatment vs. conventional OS in expected low ovarian responders.
methodsA single-centre, observational, comparative, non-experimental and retrospective study using our database at the Reproductive Endocrinology Department at Centro Médico Nacional 20 de Noviembre in Mexico City was performed.
resultsWe compared the total rFSH dosage per oocyte, we noticed a statistically significant difference between groups, Group A 388.9 vs. Group B 667.2IU per retrieved oocyte (p<0.0002, 105 to 450 IU CI 95%), Comparing total rFSH dosage per follicle, we noticed a statistically significant difference among Group A 397.5 vs. Group B 590.2IU per follicle (p<0.014, 39.2 to 346.2 IU, CI 95%).
conclusionsIn expected poor ovarian responders, mild ovarian stimulation with letrozole co-treatment is much more efficient than conventional stimulation.
