Correlation Between Serum Markers and Midluteal Phase Doppler Assessment of Uterine Arterial Blood Flow in Unexplained Recurrent Pregnancy Loss.

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
This study aimed to determine changes in uterine artery Doppler parameters in unexplained recurrent pregnancy loss (URPL) and to explore serum markers possibly associated with them. This retrospective case-control study included 107 URPL women and 107 control women. The mean pulsatility index (PI), resistive index (RI), and systolic-to-diastolic values for uterine arteries in URPL women were significantly higher than those in the controls (P < 0.05). The cutoff values of PI and RI differentiating the women with URPL from the controls were confirmed by ROC and Youden's index. Given a PI cutoff value of 2.6, the prevalence of URPL was significantly elevated in the high-PI group (74.58%) compared with that in the low-PI group (40.65%, P < 0.0001), with sensitivity and specificity of 63% and 69%, respectively. With an RI cutoff value of 0.86, the prevalence of URPL in the high-RI group (65.28%) was significantly elevated compared with that in the low-RI group (42.25%, P = 0.001), with sensitivity and specificity of 66% and 75%, respectively. The levels of serum D-dimers and anticardiolipin antibody (ACA)-IgM in URPL women were significantly higher than those in the controls. A positive correlation existed between the levels of ACA-IgM and uterine artery RI in URPL women (r = 0.43, P < 0.01). These results indicated that URPL women may be at a relatively high risk of a prothrombotic state, and the increased ACA-IgM deserves attention for its role in the elevated uterine artery Doppler parameters in URPL women.
