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

backgroundPregnancy is one of the main risk factor of pelvic floor muscle dysfunction. Postpartum women with extremely weak muscle strength have difficulty to do voluntary pelvic floor muscle training. This study aims to evaluate the effects of different protocols of electrical stimulation in the treatment of postpartum women with extremely weak muscle strength.

methodsA total of 67 women were randomized into 2 groups: group A received transvaginal electrical stimulation (TVES) for 5 times, and group B received TVES for 3 times with electromyogram (EMG)-triggered neuromuscular stimulation twice. Subjects were evaluated before and after treatment. Pelvic muscle strength was measured by both digital vaginal palpation and EMG variables, and quality of life was investigated by 4 kinds of pelvic floor disease-related questionnaires.

resultsAccording to the intention-to-treat principle, compared with baseline, in group A, EMG of contractile amplitude of endurance phase was significantly elevated (P = .03), variation of contractile amplitude in tonic phase was more stable after treatment (P = .004), and EMG of mean value of final rest was significantly elevated after treatment (P = .047). After 5 times treatments, the incidence of correct pelvic floor muscle contraction in group A was significantly elevated (P = .045). No significant difference of muscle strength test by digital vaginal palpation was detected between the 2 groups, so did questionnaires.

conclusionFor postpartum women with extremely weak muscle strength, TVES for 5 times might be more benefit for control ability of pelvic muscle contractions and elevating muscle strength even in short-time treatment.
