Changes in the Q-tip angle in relation to the patient position and bladder filling.
Article in BMC urology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05205395 (Relationship Between Q-tip Test and Urethral Hypermobility on Perineal Ultrasound for Women With Urodynamic Stress Incontinence), which is not on this map.

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.

Abstract
backgroundIt is hypothesized that patient position, supine or recline, and bladder filling status, empty or full, could change the Q-tip test result. This study evaluated the effect of the patient position and bladder filling status on the Q-tip angle for urethral hypermobility (UH).
methodsThere was a measurement of the Q-tip angle in the supine position and at a 45° angle in a reclining position during bladder emptying; and then the measurements were repeated while filling the bladder. We defined urethral hypermobility as the urethral angle straining or coughing minus that at rest ≥ 30°.
resultsAll 63 female patients (mean age: 61.6 years, range: 36-81) who complained of urinary incontinence were assessed using the Q-tip angle test. The pelvic organ prolapse quantification stages of all patients were ≤ stage 1. The mean Q-tip angle with an empty bladder was 14.1 ± 9.1° in the supine position and 16.4 ± 11.1° in the reclining position (p = 0.001). Then mean Q-tip angle during the filling bladder state was 15.4 ± 9.7° in the supine position and 15.9 ± 11.0° in the reclining position (p = 0.771). The UH rate during the bladder emptying state was 11.1 % (7/63) in the supine position and 19.1 % (12/63) in the reclining position. The UH rate during the bladder filling state was 15.0 % (9/60) in the supine position and 15.3 % (9/59) in the 45° reclining position. The odds ratio (OR) was 7.03 in the reclining position for a positive Q-tip angle. The positive rate was higher in the 45° reclining position during bladder emptying than that in the other position during bladder filling.
conclusionThe outcome of the Q-tip angle and the rate of UH changed in relation to patient position. The reclining position during bladder emptying increased the Q-tip angle, thereby resulting in a positive UH.
