1 · What the graph read from 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.

2 · The registry

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

backgroundOvarian maldescent is a rare congenital anomaly in which one or both ovaries are positioned abnormally above the pelvic brim. However, the potential relationship between ovarian maldescent and infertility remains poorly understood.

objectiveTo determine the potential relationship between ovarian maldescent and infertility.

designThis single-center, prospective cohort study included women who were diagnosed with ovarian maldescent (unilateral or bilateral) on the basis of laparoscopic findings and were assigned to the experimental group. A control group was established by randomly matching women with infertility due to tubal, ovarian, or uterine factors. Both groups were followed up for one year to assess postoperative pregnancy outcomes and the duration of preparation (DOP) for conception.

resultsA total of 21 patients were included in the ovarian maldescent group, and 42 patients were included in the control group. The non-in vitro fertilization (non-IVF) pregnancy rate was significantly higher in the control group (P = 0.005). The median DOP for conception in the ovarian maldescent group was significantly longer than controls (7 months vs. 3 months, HR = 2.927, 95% CI: 1.390, 6.165; P = 0.005). However, among those who underwent in vitro fertilization (IVF), there was no significant difference in pregnancy rates between the two groups.

conclusionsCompared to women with other infertility risk factors, those diagnosed with ovarian maldescent demonstrated a longer conception time and a lower non-IVF pregnancy rate, suggesting that ovarian maldescent per se is an independent contributor to female infertility.
