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
Purpose: Cytomegalovirus (CMV) infection represents a severe complication following hematopoietic cell transplantation (HCT), resulting in high mortality. The prevention of CMV reactivation is crucial for enhancing patient prognosis post-HCT. Letermovir prophylaxis has effectively reduced the incidence of clinically significant CMV infection (csCMVi) in adult HCT recipients. However, clinical data in pediatric patients remain limited. Patients and methods: We included 106 children who underwent HCT at our hospital between March 2019 and July 2024. The patients were grouped based on whether or not they received letermovir prophylaxis. By analyzing their general characteristics and laboratory findings, exploring the risk factors of csCMVi, and assessing the efficacy and safety of letermovir in pediatric patients. Results: Among the 106 patients, all patients were at high risk for CMV reactivation. Forty-four received letermovir prophylaxis, while 62 did not. CsCMVi occurred in 45 patients, with a significantly lower incidence in the letermovir group compared to the control group (5 [11.3%] vs 40 [64.5%], p < 0.001). Umbilical cord blood (UCB) was used in 7 patients (15.9%) in the letermovir group and in 1 patient in the control group ( Conclusion: Letermovir is both effective and safe for CMV prophylaxis in pediatric patients following HCT, especially in patients with more risk factors of csCMVi. Grade II-IV GvHD increases the risk of csCMVi, while letermovir prophylaxis reduces the risk.
