1 · What the graph read from it

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.

Abstract

The efficacy and safety of maribavir, an oral benzimidazole nucleoside that inhibits viral kinase UL97, were evaluated in hematopoietic stem cell transplant (HSCT) or solid organ transplant (SOT) recipients with cytomegalovirus (CMV) infection. This phase III, multicenter, open-label, single-arm, interventional study (ClinicalTrials.gov: NCT05137717; Japan Registry of Clinical Trials: jRCT2021210056) investigated oral maribavir 400 mg twice daily for 8 weeks. Japanese HSCT/SOT recipients aged ≥ 16 years with symptomatic or asymptomatic CMV infection (including those resistant/refractory to ganciclovir, valganciclovir, or foscarnet) and without central nervous system CMV tissue-invasive disease or CMV retinitis were enrolled. Primary endpoints were confirmed CMV viremia clearance at week 8 for efficacy and treatment-emergent adverse events (TEAEs) for safety. Among 61 patients enrolled across 22 sites, 41 patients (median age 56.0 years; 36/41 [87.8%] were HSCT recipients) received ≥ 1 maribavir dose. At week 8, twenty-eight patients (28/41, 68.3%) achieved confirmed CMV viremia clearance. Overall, 36 patients (36/41, 87.8%) had ≥ 1 TEAE, including nausea (10/41, 24.2%), anemia (7/41, 17.1%), pyrexia (6/41, 14.6%), and headache (6/41, 14.6%). Two deaths were deemed unrelated to maribavir. In conclusion, maribavir was effective in achieving CMV viremia clearance, with an acceptable safety profile and tolerability, in Japanese HSCT or SOT recipients with CMV infection.
