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
backgroundNeonatal herpes simplex virus (HSV) infection is rare but can cause severe disease, even death. However, data on neonatal HSV infection is limited in Asia. Thus, this study estimated the incidence of neonatal HSV infections and evaluated the characteristics in hospitalized patients in Korea, where seroprevalence of HSV infection in child-bearing age women is not well known.
methodsThis is the first multicenter retrospective study in 12 university hospitals in Korea. Neonates aged ≤ 28 days with confirmed HSV infection were identified from January 2008 to December 2017, and a chart review was performed.
resultsAmong 12 medical centers, 16 patients were identified in 6 centers. The estimated incidence rate was 1/7,888 in hospitalized neonates. Eight (50%) patients were males, and the median age at diagnosis was 11 days (range, 4-28 days). Ten (62.5%) patients were HSV-1-positive, and 6 (37.5%) patients were HSV-2-positive. Four (25%) patients had disseminated infection, 11 (68.8%) patients had central nervous system disease, and 1 (6.2%) patient had skin, eye, and/or mouth disease. All the patients received intravenous acyclovir, with a median treatment duration of 19 days (range, 3-68 days). Four (25%) patients received additional oral acyclovir suppressive therapy, with the median treatment duration of 5 months (3-6 months). Four patients (25%) developed seizures (one case with disseminated disease and 3 cases with central nervous system disease), and 2 of them recovered without neurologic complications. Two (12.5%) patients with disseminated disease died within 30 days from the diagnosis, and one of them had a maternal history of previous genital herpetic lesions. Medical records of maternal genital herpes were not available in 10 (62.5%) patients with neonatal HSV infections.
conclusionAlthough uncommon, neonatal HSV infection occurs in Korean babies with a high 30-day mortality of 12.5%. Increased awareness is warranted among Korean pediatricians for the early diagnosis and treatment of neonatal HSV infection.
