Effectiveness of COVID-19 Pfizer-BioNTech (BNT162b2) mRNA vaccination in adolescents aged 12-17 years: A systematic review and meta-analysis.
Synthesis in Human vaccines & immunotherapeutics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The rapid emergence of COVID-19 variants of concern (VOCs) has hindered vaccine uptake. To inform policy, we investigated the effectiveness of the BNT162b2 vaccination among adolescents against symptomatic and severe COVID-19 diseases using mostly real-world data (15 studies). We searched international databases until May 2022 and used Cochrane's risk of bias tools for critical appraisal. Random effects models were used to examine overall vaccine effectiveness (VE) across studies (general inverse-variance) and the effect of circulating VOCs on VE (log relative ratio and VE). Meta-regression assessed the effect of age and time on VE (restricted-maximum likelihood). BNT162b2 VE against PCR-confirmed SARS-CoV-2 was 82.7% (95%CI: 78.37-87.31%). VE was higher for severe (88%) than non-severe (35%) outcomes and declining over time improved following booster dose in omicron era [73%(95%CI:65-81%)]. Fully vaccinated adolescents are protected from COVID-19 circulating VOCs by BNT162b2 especially for the need of critical care or life support.
