1 · What the graph read from it

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.

2 · The registry

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 objective was to compare postoperative urinary retention using the Babcock and Kelly clamps for retropubic midurethral sling (RPS) tensioning.

methodsThis was a retrospective cohort of isolated RPS procedures from December 2010 through April 2016 by five fellowship-trained surgeons at two institutions. Slings were tensioned with a Babcock clamp by grasping a 3-mm midline fold of mesh (RPS-B) or a Kelly clamp as a spacer between the sling and suburethral tissue (RPS-K). Assessment of urinary retention included the primary outcome of postoperative catheterization and several secondary outcomes, including discharge home with a catheter, within 1 year of surgery. Analysis of covariance was used to compute the mean difference in duration of catheterization and log-binomial regression was used to calculate risk ratios (RR) and 95% confidence intervals (CI).

resultsWe included 240 patients. The RPS-B group had a lower body mass index and was more likely to be menopausal, have had pelvic organ prolapse surgery, and have a lower maximum urethral closure pressure than the RPS-K group. The mean duration of catheterization was similar, as demonstrated by the crude (0.21 days [-0.30-0.71]) and BMI-adjusted (0.07 days [-0.41-0.55]) mean difference in duration of catheterization. The incidence of postoperative OAB symptoms was comparable between the groups (BMI-adjusted RR: 0.95 (0.80-1.1)), and the incidence of revision did not differ (p = 0.7).

conclusionsThe Babcock and Kelly clamp tensioning techniques appear comparable, with a low incidence of prolonged postoperative catheterization. Most catheters were removed on the day of the surgery. It is reasonable to tension retropubic midurethral slings with either method.
