Valsalva leak point pressure-associated Q-tip angle and simple female stress urinary incontinence symptoms.

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
purposeTo clarify the association between clinically defined simple stress urinary incontinence (SUI) symptoms and urodynamic SUI, we examined the relationship between Valsalva leak point pressure (VLPP) as measured by the Q-tip test and Stamey grade in simple female SUI.
methodsTwo hundred grade I or II female SUI patients with SUI symptom were examined by reviewing medical history; physical examination; urethral mobility as assessed by Q-tip test; stress test; and cystometry, including VLPP measurement. On the basis of the VLPP, patients were classified into urethral hypermobility [UH, subdivided into anatomical incontinence (AI) and equivocal incontinence (EI)] or intrinsic sphincter deficiency groups for analysis of the relationship between VLPP and Stamey grade and Q-tip angle.
resultsSeventy-eight patients were included, and the mean patient age was 54 ± 7.5 years, mean SUI symptom duration 2.8 years (range 0.5-6 years), mean VLPP 103.6 ± 18.4 cm H2O, and mean Q-tip angle 28.6° ± 7.2°. Fifty-three patients were categorized as Stamey grade I, 25 as Stamey grade II, 51 as AI, and 27 as EI. VLPP was found to be negatively correlated with Q-tip angle (Rs = -0.798, Y = -0.313X + 60.95, P < 0.001), and classifications of VLPP and Stamey grade have positive correlation (χ (2) = 4.9130, P = 0.0267).
conclusionsIn simple female SUI, VLPP is associated with the Q-tip angle and Stamey grade, which may help to reduce some of urodynamic items.
