1 · What the graph read from 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.

2 · The registry

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

Introduction: Wastewater and environmental surveillance (WES) is a valuable supplementary tool to clinical surveillance for infectious diseases, especially in low- and middle-income countries. This systematic review evaluates laboratory methods for detecting Methods: The review was performed using protocol registered with PROSPERO (ID: CRD42024573052) following PRISMA 2020 guidelines. The review was funded by the European Commission's Health Emergency Preparedness and Response Authority (HERA) and the World Health Organization (WHO). Search was conducted in PubMed, EMBASE, and Web of Science (last update: May 31, 2025). Studies describing sampling and laboratory methods for Results: Of 2,007 records, 94 studies from 36 countries met inclusion criteria. Grab sampling was most common, followed by trap and composite sampling. Detection methods included culture, PCR, and sequencing. Six methodological pathways were identified. Fewer than 14% of studies reported comprehensive quality control. Substantial heterogeneity in sampling, handling, and testing protocols affected reproducibility and comparability. Discussion: Evidence generated was constrained due to inconsistent reporting of quality control and validation criteria. Most studies lacked critical methodological details for reproducibility and scale-up. Harmonized, context-adapted protocols and minimum reporting standards are needed, along with leveraging existing surveillance infrastructure for rapid implementation of Systematic review registration: https://www.crd.york.ac.uk/PROSPERO/view/CRD42024573052, identifier PROSPERO (CRD42024573052).
