A novel disposable intrauterine infusion catheter reduces pain and shortens procedure time compared to a conventional balloon-tipped catheter in sonohysterography: a retrospective cohort study.

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 compare pain scores and complication rates between a novel disposable intrauterine infusion catheter (Yikai Medical) and a conventional balloon-tipped 12F double-lumen catheter during hysterosalpingo-contrast sonography (HyCoSy).
methodsThis single-center retrospective cohort study included 128 infertile women who underwent HyCoSy between January 2022 and June 2023. Patients were divided into observation group (disposable catheter, n = 64) and control group (balloon catheter, n = 64). Primary outcomes were Visual Analog Scale (VAS) pain scores (intraoperative, 30 min, 2 h postoperative) and complication rates. Secondary outcomes included procedure time and imaging success rate. Multivariate logistic regression was used to identify independent predictors of pain.
resultsBaseline characteristics were generally comparable between the groups, although patients in the observation group were slightly younger (P = 0.041). VAS scores were significantly lower in the observation group at all time points (all P<0.001). Overall complication rate was lower in the observation group (15.6% vs. 29.7%) but not statistically significant (P = 0.091). Procedure time was shorter in the observation group (8.28 ± 1.44 vs. 10.49 ± 2.32 min, P<0.001). Imaging success was similar (100% vs. 98.4%, P = 1.000). Catheter type was an independent predictor of moderate-to-severe pain (OR = 0.115, 95% CI 0.050-0.267, P<0.001).
conclusionThe disposable intrauterine infusion catheter significantly reduces pain and procedure time during HyCoSy compared to the conventional balloon-tipped catheter, with comparable imaging success and a trend toward fewer complications.
