The timing of intravenous oxytocin administration is crucial to minimize perioperative blood loss during first-trimester suction curettage for missed abortion.

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
backgroundOxytocin is commonly used to reduce blood loss during suction curettage for missed abortion. However, the potential of oxytocin to mitigate blood loss in early pregnancy remains controversial. Based on the hypothesis that the "timing" of oxytocin administration may be a critical factor, we investigated whether the timing of intravenous (IV) administration is associated with reduced perioperative blood loss during first-trimester suction curettage for missed abortion.
methodsThe medical charts of 146 patients with ultrasound-confirmed first-trimester missed abortion who underwent suction curettage with IV oxytocin administration were retrospectively reviewed.
resultsAmong the patients, 67 received 10 IU of IV oxytocin before suction curettage (early-oxytocin administration group), while 79 patients received 10 IU of IV oxytocin after suction curettage (late-oxytocin administration group). The demographic features between the two groups did not significantly differ. However, there was a lower proportion of nulliparous patients in the early-oxytocin administration group than in the late-oxytocin administration group (38.8% vs 60.8%, p = 0.006). The perioperative blood loss amount was significantly lower in the early-oxytocin administration group than in the late-oxytocin administration group (60 [range: 50-100] vs 100 [range: 30-250] mL, p = 0.001). Moreover, the multivariate logistic regression analysis showed that the early-oxytocin administration group had a lower risk for a perioperative blood loss amount of ≥100 mL than the late-oxytocin administration group (0.23 [range: 0.10-0.55], p = 0.001); a gestational age of 9-12 weeks ( p = 0.009) was found to be associated with an increased risk for a perioperative blood loss amount of ≥100 mL.
conclusionCompared with late-oxytocin administration, early-oxytocin administration could reduce perioperative blood loss during first-trimester suction curettage for missed abortion. However, the results require further investigation.
