From benchmarking to global leadership: Singapore's health sciences authority's journey to WHO maturity level 4 and WHO-Listed Authority status for medicines.

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 article aims to describe Singapore Health Sciences Authority's (HSA's) multi-year journey to attaining World Health Organisation (WHO) Maturity Level 4 (ML4) and WHO-Listed Authority (WLA) status for medicines regulatory functions, presenting HSA as a descriptive policy case study on the practical application of the WHO Global Benchmarking Tool (GBT) and WLA frameworks. It outlines the benchmarking and Performance Evaluation (PE) processes, including the scope of assessment, phased reviews, and key milestones achieved between 2021 and 2024. HSA became the first regulator globally to achieve ML4 for medicines, before progressing through the WLA Performance Evaluation and eventually securing WLA listing across all medicines' regulatory functions. The article examines the institutional factors that enabled these achievements, including strong governance, sustained leadership commitment, technical expertise, digitalised regulatory workflows, and close engagement with international partners. The findings highlight that ML4 and WLA recognition are not merely markers of national regulatory excellence, but strategic enablers that strengthen regulatory credibility, support international reliance by other authorities, and contribute to more timely access to safe, effective, and quality-assured health products. HSA's experience also underscores that attaining and sustaining advanced regulatory maturity requires long-term investment in systems, people, oversight, and innovation, particularly as regulatory agencies take on broader roles in supporting regional and global public health.
