Measurement of the Q-tip angle before and after tension-free vaginal tape-obturator (TVT-O): preoperative urethral mobility may predict surgical outcome.
Article in International urogynecology journal, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
introduction and hypothesisThe purpose of this study was to compare the results of the Q-tip test before and after the tension-free vaginal tape-obturator (TVT-O) in women with stress urinary incontinence (SUI) to determine the value of the Q-tip test in predicting the outcome of transobturator tape (TOT).
methodsBetween June 2008 and June 2009, 59 women with SUI who underwent the TVT-O procedure and were followed up for at least 6 months were analyzed. Urethral hypermobility was defined as a maximal straining angle greater than 30° as measured by the Q-tip test. Parameters of evaluation included a comprehensive medical history, physical examination, Q-tip test, stress test, and urodynamic study, which included determination of the Valsalva leak point pressure. Cure was defined as no leakage of urine postoperatively either subjectively or objectively, whereas failure was defined as the objective loss of urine during the stress test.
resultsThe patients were divided into two groups according to their preoperative Q-tip angle: <30° (group 1, n=21) and ≥30° (group 2, n=38). The Q-tip angle decreased significantly in both groups: from 25.9 ± 5.98° preoperatively to 18.4 ± 7.23° postoperatively in group 1 (p=0.04) and from 36.6 ± 6.75° preoperatively to 24.1 ± 5.48° postoperatively in group 2 (p=0.03). The difference was obviously pronounced in group 2. The incontinence cure rate was significantly higher in group 2 (97.4 %) than in group 1 (85.7 %; p=0.04).
conclusionsOur results suggest that mobility of the proximal urethra is associated with a high rate of success of the TVT-O procedure.
