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: Surgical systems in Southeast Asia were already experiencing significant supply shortages before the COVID-19 pandemic, which further exacerbated these deficits. With the aim of identifying modifiable factors for improvement, our study benchmarks surgical system efficiencies of eight Southeast Asian Hospital and Health Systems' (HHS) in combating COVID-19, with an analysis spanning three levels: country, city and HHS. Methods: Based on 18-month data (January 2020 to June 2021), we developed a two-stage frontier benchmarking approach that applies efficiency benchmarking techniques to evaluate how close organisations operate relative to an efficiency frontier (representing the maximum potential output achievable with a given set of inputs). Stage 1 involves data envelopment analysis, which yields monthly national efficiency scores for five countries based on country-level panel data. Stage 2 involves stochastic frontier analysis, followed by evaluating HHS-level efficiency with HHS-level data over 64 possible model configurations, adjusting for stage 1 national-level efficiency scores as well as city-level responses. Results: Among the 64 possible stage 2 model configurations, two model clusters comprising 36 plausible models demonstrated superior fit to the observed data, thereby providing robust insights through majority voting. Policy measures related to access control and workplace closure were positively associated with recovery rates. Elective surgery volumes showed a negative association and emergency surgery volumes a positive association with efficiency. Our analysis indicates lags of 0-1 month between input changes and effects on the surgical system. Conclusions: Insights from the benchmarking of HHS efficiencies will help inform surgical system policy and responses. Access control and workplace closure policies are associated with COVID-19 recovery rates. Emergency surgery volumes are associated with higher efficiency and elective surgery volumes with lower efficiency. System responses to policy measures can manifest with lags of up to a month. Considering insights from multiple plausible models makes these conclusions more robust.
