Influence of Women´s Residence Region on Assisted Reproduction Treatments - Experience of a Tertiary Center in Northern Portugal.
Article in JBRA assisted reproduction, 2022. 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
objectiveData on the possible influence of women´s region of residence, within the same country, on the outcomes of medically assisted reproduction cycles are scarce. This study aims to assess the impact of the women's region of residence on the results of in-vitro fertilization cycles.
methodsWe evaluated in-vitro fertilization cycles between 2010 and 2017, performed in a northern Portugal assisted reproduction center. We defined two groups: Douro Litoral (group 1; n=783), and Trás-os-Montes and Alto Douro (group 2; n=178). We analyzed demographics and cycle-related variables, and we calculated the rates for embryo transfer cycles. We used the Mann-Whitney and Chi-square tests and p<0.05 was considered statistically significant.
resultsWe included 961 cycles. The region of residence had no effect on the following variables: women´s age; body mass index; or duration of infertility (p>0.05). Group 2 had a statistical significant lower number of previous cycles than group 1 (1.3±0.5 and 1.5±0.7; p=0.005). In the sub-analysis of cycles with embryo transfer (n=781), group 1 obtained had rates of normal fertilization (62.5% vs. 57.5%; p=0.04), miscarriage rate (30.0 vs. 10.9%; p=0.007), and lower implantation rates compared to group 2 (33.3% vs. 50.0%; p<0.001).
conclusionsWomen from the region of Trás-os-Montes e Alto Douro had a lower number of previous cycles, compared to those from the Douro Litoral, despite the absence of statistical significant differences in terms of age or infertility duration. These findings reinforce the need to contemplate the sociodemographic and socioeconomic variables in this context.
