Accuracy of Home-Based Ultrasonographic Diagnosis of Obstetric Risk Factors by Primary-Level Health Care Workers in Rural Nepal.

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 assess the feasibility of ultrasonographic task shifting by estimating the accuracy at which primary-level health care workers can perform community-based third-trimester ultrasound diagnosis for selected obstetric risk factors in rural Nepal.
methodsThree auxiliary nurse-midwives received two 1-week ultrasound trainings at Tribhuvan University Teaching Hospital in Kathmandu. At a study site in rural Nepal, pregnant women who were 32 weeks of gestation or greater were enrolled and received ultrasound examinations from the auxiliary nurse-midwives during home visits. Each auxiliary nurse-midwife screened for noncephalic presentation, multiple gestation, and placenta previa. Deidentified digital ultrasonograms were stored and uploaded onto an online server, where certified sonologists and ultrasonographers reviewed the images and made their own diagnoses for the three conditions. Accuracy of auxiliary nurse-midwife diagnoses was then calculated.
resultsA total of 804 women contributed to the analysis. Each auxiliary nurse-midwife's κ statistic for diagnosis of noncephalic presentation was above 0.90 compared with the ultrasonogram reviewers. Sensitivity, specificity, and positive and negative predictive values were between 90% and 100% for all auxiliary nurse-midwives. For multiple gestation, the auxiliary nurse-midwives were in perfect agreement with both the ultrasonogram reviewers and maternal postpartum self-report. Two placenta previa cases were detected, and the ultrasonogram reviewers agreed with both.
conclusionWith limited training, primary-level health care workers in rural Nepal can accurately diagnose selected third-trimester obstetric risk factors using ultrasonography.
