Relationship between semen regurgitation and pregnancy rates with intrauterine insemination.
Article in Fertility and sterility, 2021. 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
objectiveTo evaluate the relationship between semen regurgitation and intrauterine insemination (IUI) outcomes. We hypothesized that clinical pregnancy rates and live birth rates would be reduced when regurgitation occurred.
designRetrospective cohort study.
settingA university-based reproductive endocrinology and infertility clinic. PATIENT(S): Retrospective review of 1,957 IUI cycles performed on 660 patients between July 2007 and May 2012. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The primary outcome was live birth. Secondary outcomes were positive serum pregnancy result and clinical pregnancy. Risk ratios (RRs) and 95% confidence intervals (CIs) were calculated using a cluster-weighted generalized estimating equations method to estimate modified Poisson regression models with robust standard errors to account for multiple IUI cycles in the same patient. RESULT(S): Live birth rates were similar in IUI cycles with and without regurgitation (6.3% vs. 6.8%, respectively, RR = 0.82, 95% CI [0.53-1.26]). Clinical pregnancy rates in the presence or absence of regurgitation were 10.5% vs. 10.0% (RR = 0.99, 95% CI [0.73-1.35]). Positive serum pregnancy tests after IUI did not differ by regurgitation status (15.0% vs. 15.4%, RR = 0.97, 95% CI [0.75-1.24]). Results were unchanged when adjusted for covariates (age, race and ethnicity, body mass index, duration of infertility, medication, infertility diagnosis, total motile count, and method of sperm preparation). CONCLUSION(S): The presence of regurgitation during the IUI procedure is not related to pregnancy outcome.
