Cervical pessary for preterm twin pregnancy in women with a short cervix.

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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe aimed to evaluate the effectiveness of cervical pessary for extending twin pregnancy in women with a short cervix.
methodsBetween January 2014 and March 2019, the use of a cervical pessary for twin pregnancy in women with a cervical length of ≤15 mm was investigated between 16 and 28 weeks of gestation. We included women with a shortened cervix after a cerclage procedure and visible fetal membranes and cervical dilatation. Thirteen patients underwent pessary insertion and were matched with a control group of 15 patients. Pregnancy and neonatal outcomes were compared between the groups. We excluded women with major fetal anomalies discovered before or after birth and known placenta previa.
resultsWomen who underwent pessary insertion were diagnosed with a short cervix (0.65±0.47 vs. 0.66±0.51 cm in the pessary and control groups, respectively;
conclusionThe use of a cervical pessary may prolong gestation in twin pregnancies in women with an extremely short cervix until viable gestational age.
