Efficacy and safety of nirmatrelvir/ritonavir (Paxlovid) for COVID-19: A rapid review and meta-analysis.

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
This study aimed to examine the efficacy and safety of nirmatrelvir/ritonavir (Paxlovid) for coronavirus disease 2019 (COVID-19). PubMed, Cochrane Library, Web of Science, medRxiv, and Google Scholar were searched to identify the relevant evidence up to November 10, 2022. The reference lists of key studies were also scanned to find additional records. The quality of the studies was evaluated using the Cochrane tools for assessing the risk of bias. The Comprehensive Meta-Analysis software version 3.0 was employed for data analysis. Twenty-three studies involving 314 353 patients were included in the analysis. The findings of the meta-analysis showed a significant difference between the Paxlovid and no-Paxlovid groups in terms of mortality rate (odds ratio [OR] = 0.25; 95% confidence interval [CI]: 0.14-0.45), hospitalization rate (OR = 0.40; 95% CI: 0.24-0.69), polymerase chain reaction negative conversion time (mean difference [MD] = -2.46; 95% CI: -4.31 to -0.61), and hospitalization or death rate (OR = 0.17; 95% CI: 0.06-0.46). However, no significant difference was observed between the two groups in terms of COVID-19 rebound (OR = 0.84; 95% CI: 0.67-1.04), emergency department visit (OR = 0.75; 95% CI: 0.45-1.24), intensive care unit admission (OR = 0.37; 95% CI: 0.13-1.01), and adverse events (OR = 2.20; 95% CI: 0.42-11.47). The results of the present study support the efficacy and safety of Paxlovid in the treatment of patients with COVID-19. Further research is needed to investigate the COVID-19 rebound after Paxlovid treatment.
