Pregnancy Outcomes After Second Trimester Pregnancy Loss and Termination for Medical Reasons Before 24 Weeks: A Historical Cohort Study [PASTeL-2].

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
objectiveTo investigate if second trimester pregnancy loss (second trimester miscarriage [STM] or termination for medical reasons [TFMR]) was associated with subsequent adverse pregnancy outcomes.
designRetrospective cohort study.
settingConducted using the Aberdeen Maternity and Neonatal Databank [AMND] in Aberdeen, United Kingdom. POPULATION: Women with and without a history of STM or TFMR (between 13 + 0 and 23 + 6 weeks' gestation).
methodsLogistic and linear regression were used to determine associations between exposed (prior STM or TFMR) and unexposed women (women with prior livebirth).
main outcome measuresThe primary outcome was subsequent spontaneous preterm birth, defined as spontaneous onset of labour and birth between 24 + 0 and 36 + 6 weeks' gestation.
resultsThe study included 65 592 women with first and second pregnancies recorded from 1950 to 2017. Women who had a STM in their first pregnancy (n = 935) were at significantly greater risk of spontaneous preterm birth in the next pregnancy (4.3% vs. 1.5%; adjusted Odds Ratio [aOR] 2.55 (95% CI 1.81 to 3.50); p < 0.01). Women with STM in their first pregnancy were two-fold more likely to have a repeat second trimester miscarriage (3.7% vs. 1.1%; aOR 2.25 (95% CI 1.53 to 3.19); p < 0.01). Women who had a first TFMR (n = 177) were significantly more likely to have a repeat TFMR (adjusted OR [aOR] 6.59 (3.4% vs. 0.3%, 95% CI 2.54 to 13.99); p < 0.01). There was no observed increased risk of spontaneous preterm birth after TFMR detected in this sample (aOR 1.06 (95% CI 0.39 to 2.87); p = 0.91) though the sample size was too small to be conclusive.
conclusionsWomen with a history of second trimester pregnancy loss have an increased risk of adverse pregnancy outcomes in a subsequent pregnancy. Consequently, antenatal care surveillance and counselling may need to be increased for women with a prior STM, who are at risk of spontaneous preterm birth and other adverse obstetric outcomes including pre-eclampsia. Women after TFMR can be reassured by our findings; however, larger cohorts are needed to confirm these results.
