Nirmatrelvir Plus Ritonavir: First Approval.
Review in Drugs, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. It is linked to trial NCT05749445 (Appropriate Evaluation of Antiviral Therapy With Nirmatrelvir-ritonavir in Hospitalized Patients), which is not on this map. Cited by 157 papers, 2 of them syntheses that pooled 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.
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
Nirmatrelvir plus ritonavir (Paxlovid™; Pfizer) is a co-packaged combination of nirmatrelvir and ritonavir tablets, intended for co-administration and developed for the treatment and post-exposure prophylaxis of coronavirus disease 2019 (COVID-19). Nirmatrelvir is a peptidomimetic inhibitor of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease, while ritonavir is a human immunodeficiency virus type 1 (HIV-1) protease inhibitor and CYP3A inhibitor. Nirmatrelvir plus ritonavir received its first conditional authorization in December 2021 in the United Kingdom, for the treatment of COVID-19 in adults who do not require supplemental oxygen and who are at increased risk for progression to severe COVID-19. In January 2022, nirmatrelvir plus ritonavir received authorization in the EU for use in the same indication. Nirmatrelvir plus ritonavir is authorized for emergency use in the USA. This article summarizes the milestones in the development of nirmatrelvir plus ritonavir leading to its first authorizations and approval for the treatment of COVID-19.
