Evaluation of the Live-Attenuated Intranasal Respiratory Syncytial Virus (RSV) Vaccine RSV/6120/ΔNS2/1030s in RSV-Seronegative Young Children.
Trial report in The Journal of infectious diseases, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03387137 (Phase I Placebo-Controlled Study of the Infectivity, Safety and Immunogenicity of a Single Dose of a Recombinant Live-Attenuated Respiratory Syncytial Virus Vaccine, RSV 6120/∆NS2/1030s, Lot RSV#012A, Delivered as Nose Drops to RSV-Seropositive Children 12 to 59 Months of Age and RSV-Seronegative Infants and Children 6 to 24 Months of Age), which is not on this map.

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.

Abstract
backgroundRespiratory syncytial virus (RSV) is the leading cause of pediatric lower respiratory illness (LRI) and a vaccine for immunization of children is needed. RSV/6120/ΔNS2/1030s is a cDNA-derived live-vaccine candidate attenuated by deletion of the interferon antagonist NS2 gene and the genetically stabilized 1030s missense polymerase mutation in the polymerase, conferring temperature sensitivity.
methodsA single intranasal dose of RSV/6120/ΔNS2/1030s was evaluated in a double-blind, placebo-controlled trial (vaccine to placebo ratio, 2:1) at 105.7 plaque-forming units (PFU) in 15 RSV-seropositive 12- to 59-month-old children, and at 105 PFU in 30 RSV-seronegative 6- to 24-month-old children.
resultsRSV/6120/ΔNS2/1030s infected 100% of RSV-seronegative vaccinees and was immunogenic (geometric mean RSV plaque-reduction neutralizing antibody titer [RSV-PRNT], 1:91) and genetically stable. Mild rhinorrhea was detected more frequently in vaccinees (18/20 vaccinees vs 4/10 placebo recipients, P = .007), and LRI occurred in 1 vaccinee during a period when only vaccine virus was detected. Following the RSV season, 5 of 16 vaccinees had ≥4-fold rises in RSV-PRNT with significantly higher titers than 4 of 10 placebo recipients with rises (1:1992 vs 1:274, P = .02). Thus, RSV/6120/ΔNS2/1030s primed for substantial anamnestic neutralizing antibody responses following naturally acquired RSV infection.
conclusionsRSV/6120/ΔNS2/1030s is immunogenic and genetically stable in RSV-seronegative children, but the frequency of rhinorrhea in vaccinees exceeded that in placebo recipients. CLINICAL TRIALS REGISTRATION: NCT03387137.
