Do trained reproductive endocrinologists perform better than their trainees? Comparing clinical pregnancy rates and live birth rates after transfer of single fresh blastocysts.
Article in Journal of assisted reproduction and genetics, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 compare clinical pregnancy rates and live birth rates of single blastocyst transfers performed by attending physicians or fellows in reproductive endocrinology and infertility program.
methodsRetrospective study in an academic reproductive center. We evaluated 932 fresh single blastocyst transfer cycles performed by fellows in training (389 embryo transfers) and by attending physicians (543 embryo transfers).
resultsThere were no differences in the baseline characteristics and IVF cycle parameters between patients who had transfers performed by fellows or attending physicians. Transfers performed by attending physicians or fellows resulted in similar CPR (46.5 vs. 42.9%, p = 0.28) and LBR (38.3 vs. 34.2%, p = 0.11). Multivariate logistic regression analysis showed that even after adjusting for possible confounders (age, gravity, parity, baseline FSH, antral follicle count, dose of gonadotropins, stimulation protocol, and quality of embryo transferred), CPR (OR 0.81, CI 0.62-1.07) and LBR (OR 0.79, CI 0.6-1.05) in the two groups were comparable.
conclusionClinical pregnancy rate and live birth rate after embryo transfer performed by attending staffs or fellows are comparable. This finding reassures fellowship programs that allowing fellows to perform embryo transfers does not compromise the outcome.
