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

purposeAntispasmodics like phloroglucinol are commonly used to alleviate pain. Various authorities recommend the use of this drug for conditions such as dysmenorrhoea, threatened abortion or labour pains. The goal was to carry out a systematic review analysing the existing data concerning the efficacy of phloroglucinol to treat pain in obstetrical or gynaecologic cases. The protocol was registered in Prospero (CRD 42018094065).

methodsThe keywords "phloroglucinol" and "randomised controlled trials" were used to search Medline, Embase and the Cochrane Library. We selected randomised, controlled against placebo trials testing the effect of phloroglucinol on gynaecologic or obstetrical pain either as a primary or secondary endpoint. We excluded trials exploring pain caused by intestinal, renal, metabolic or other causes and trials that were not available for critical review in either English or French. A quantitative synthesis (meta-analysis) was planned if the included trials were sufficiently homogenous. If this were not the case, a descriptive synthesis would be presented.

resultsTwelve trials identified studied the effect of phloroglucinol in gynaecologic or obstetrical conditions. Only two trials corresponded to the inclusion criteria of this review, one of which was not available for critical review.

conclusionsPhloroglucinol is not well evaluated in this field. Whether for labour pains, abortion pains or benign gynaecologic pains, the results found are insufficient to promote the use of this drug in these indications.
