Impact of Covid-19 control strategies on health and GDP growth outcomes in 193 sovereign jurisdictions.

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 Covid-19 pandemic caused approximately 27.3 million excess deaths globally as of June 2024. Despite growing research on pandemic response factors, the effectiveness of different strategic approaches to Covid-19 control remains insufficiently investigated. We aimed to examine associations between Covid-19 pandemic control strategies (including stringent border restrictions) with age-standardized excess mortality and GDP per capita growth outcomes during 2020-2021. We analyzed 193 sovereign jurisdictions with existing Global Burden of Disease Study data. Jurisdictions were classified by implementation of exclusion/elimination strategies reported in published literature, and the level of border restriction measures based on the Oxford Stringency Index. Multivariable analyses adjusted for island status, GDP per capita, and an index of government corruption. Excess mortality was cube root transformed and GDP per capita log transformed for regression analysis. Jurisdictions implementing explicit exclusion/elimination strategies showed the lowest cumulative age-standardized excess mortality (-2.1/100,000) compared to others (166.5/100,000). Island jurisdictions experienced lower mortality (64.8/100,000) than non-islands (194.3/100,000). Duration of border restrictions correlated with reduced excess mortality in islands (Pearson's r = -0.624, p < 0.001; β -0.004, island interaction -0.005, p < 0.001), but not in non-islands. However, this effect weakened when controlling for government corruption in a subsample (lower corruption was associated with lowered mortality). No consistent significant relationships emerged between border measures and GDP growth, suggesting that stringent border restrictions in a pandemic may not significantly harm economies. We concluded that exclusion/elimination strategies and related stringent border restrictions were associated with better health outcomes, particularly for islands. Effectiveness was likely partially mediated by governance quality. Future pandemic planning should consider both control strategy selection and implementation context, both of which are modifiable.
