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

BACKGROUND AND

objectivesGenitourinary syndrome of menopause (GSM) is a common condition affecting of most postmenopausal women, which greatly impacks the quality of life,and need to treat. This prospective multicenter cohort study aimed to compare the efficacy and safety of the fractional carbon dioxide (CO STUDY DESIGN/MATERIALS AND

methodsThis study included 162 postmenopausal patients who received vaginal laser or topical Estriol cream therapy between January 2017 and May 2019 at eight study centers in China. The degree of GSM-related symptoms (vaginal burning, dryness, and dyspareunia) was evaluated using the Vaginal Health Index score (VHIS) and Visual Analog Scale (VAS) at baseline, 1, 3, 6, and 12 months posttreatment. The primary endpoint was the improvement in vaginal burning, dryness, and dyspareunia at 6 months after treatment. Multivariate logistic regression was used to compare the rate of improvement in the two groups.

resultsAt baseline, the laser and control groups showed no significant difference in the mean age, time after menopause, and the VHIS (all P > 0.05). In the laser group, compared with baseline, significant differences were seen in the VHIS after the first or second treatment session and at 1, 3, 6, and 12 months posttreatment (P < 0.01). In the control group, compared with baseline, the VHIS showed significant differences after 1, 3, and 6 months of treatment (P < 0.05). However, there was no significant difference after 3 and 6 months of follow-up between the two groups (P > 0.05). The VHIS scores were significantly higher after 1 month (16.63 ± 2.79 vs. 15.57 ± 2.43) and 12 months (15.72 ± 2.59 vs. 12.12 ± 4.08) of treatment in both the groups (P < 0.05). At 6 months after treatment, both groups showed improvement in vaginal burning, vaginal dryness, and dyspareunia (P > 0.05). The VAS findings at 6 months posttreatment were significantly different when compared with the pretreatment findings (P < 0.001). There were no significant adverse effects in the two groups.
