Efficacy and Safety of Low-Dose, Rapidly Infused Bamlanivimab and Etesevimab: Phase 3 BLAZE-1 Trial for Mild-to-Moderate COVID-19.
Article in Infectious diseases and therapy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04427501 (A Randomized, Double-blind, Placebo-Controlled, Phase 2/3 Study to Evaluate the Efficacy and Safety of LY3819253 and LY3832479 in Participants With Mild to Moderate COVID-19 Illness), 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.

Abstract
introductionThe monoclonal antibody therapies bamlanivimab (BAM) + etesevimab (ETE) received emergency use authorization (EUA) from the US Food and Drug Administration (February 9, 2021) for treatment of mild-to-moderate COVID-19. The EUA of BAM + ETE was revoked (December 14, 2023) due to the high prevalence of BAM + ETE-resistant variants of SARS-CoV-2. Efficacy and safety of 700/1400 mg and 2800/2800 mg BAM + ETE are well established and published; however, efficacy and safety of 350/700 mg BAM + ETE have not been disclosed to date.
methodsThis portion of phase 3, BLAZE-1 trial (J2X-MC-PYAB) enrolled patients (between June 17, 2020 and April 9, 2021) with mild-to-moderate COVID-19 within 3 days of laboratory diagnosis of SARS-CoV-2 infection. In total, 354 patients with at least one risk factor for severe COVID-19 were enrolled, randomized (2:3), and infused with placebo (N = 141) or 350/700 mg BAM + ETE (N = 213), over ~ 8 min. Primary endpoint was to assess proportion of patients with persistently high SARS-CoV-2 viral load (PHVL) (log viral load > 5.27) 7 days after infusion.
resultsPatients were aged (mean) 53 years, 49.7% female, and 82.7% White. Seven days after drug infusion, 10.8% (95% confidence interval: 6.6, 15.0; p < 0.001) of BAM + ETE-treated patients and 34.8% (26.9, 42.6) of placebo-treated patients had PHVL, and the viral load change from baseline (least square mean [standard error]) was - 3.50 (0.15; p < 0.001) in BAM + ETE-treated patients versus - 2.51 (0.19) in placebo-treated patients. The majority of treatment-emergent adverse events were considered mild or moderate in severity (BAM + ETE: 6.6%; placebo: 14.2%). No deaths were reported.
conclusionsConsistent with previous studies, patients treated with BAM + ETE (350/700 mg) had a significantly lower proportion of PHVL and greater reduction in viral load compared with placebo. The overall safety profile is consistent with higher doses of BAM + ETE. Infusions of over ~ 8 min did not result in meaningful increase in incidence of TEAEs compared to higher doses of BAM + ETE administered over 30-60 min.
