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 estimate the association between the New York State coronavirus disease 2019 (COVID-19) lockdown and preterm birth rates among individuals with Medicaid insurance overall and by onset of delivery, and to investigate contemporaneous changes in stillbirth rates.
methodsWe used New York State Medicaid claims to conduct a quasi-experimental study of 2018-2020 hospital deliveries of liveborn neonates. We estimated the effect of the state's lockdown policy (New York State on PAUSE) on preterm birth by comparing changes in preterm birth rates before (January 1-March 21, 2020) and during the lockdown (March 22-June 8, 2020) with changes before and during the same dates in the 2 years earlier using difference-in-difference models. We stratified models into spontaneous and medically indicated preterm births. As a secondary outcome, we estimated the effect of the lockdown on stillbirth rates per 100 live births.
resultsThere were 38,272 hospital deliveries to individuals with Medicaid insurance from January 1 to June 8, 2020, and 81,054 on the same dates in 2018 and 2019. From January to March 21, 2020, the preterm birth rate was 10.0%; roughly half were spontaneous. Using difference-in-difference models, New York State on PAUSE was associated with a nearly 1 percentage point decline (-0.93, 95% CI, -1.64 to -0.21) in the preterm birth rate. The overall difference was larger when the time period was limited to the first half of the lockdown (-1.07, 95% CI, -1.95 to -0.20). Rates of both spontaneous and medically indicated preterm birth decreased, but only the change in the rate of medically indicated preterm births was statistically significant (-0.58, 95% CI, -1.08 to -0.08). New York State on PAUSE was not associated with any change in stillbirth rates.
conclusionThe New York State COVID-19 lockdown was associated with a modest decline in preterm birth rates, particularly medically indicated preterm birth; there was no change in stillbirth rates. This association was particularly strong in the early part of the pandemic and was slightly more weighted toward medically indicated preterm births.
