Effect of physical distancing on Covid-19 incidence in Brazil: does the strictness of mandatory rules matter?
Article in Health policy and planning, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
This study aims to examine the association between physical distancing measures and coronavirus disease 2019 (COVID-19) incidence among Brazilian states. We divided the methodology was divided into three steps. In the first step, we used nationwide global positioning system daily data to estimate country and state-level physical distancing and examined the association with COVID-19 incidence through a Generalized Additive Model. Secondly, using National Household Sample Survey COVID19 data, a cluster analysis categorized the Brazilian states into different categories of physical distancing policies promoting adoption and political inclination of their governments. Finally, through a Poisson Regression Model, we examined the association of state physical distancing with variables related to the socio-economic situation, test coverage and early adoption of policies promoting physical distancing of each state. Physical distancing effects on reduction of COVID-19 spread are heterogeneous among states. Estimation of incidence rate ratio (IRR) suggests that in a scenario of 100% of social isolation incidence of COVID-19 will have reached approximately only 2.6% of the magnitude compared to when there is no social isolation for Brazil [95% confidence interval (CI) 0.8-8.3]. Only a 10% increase in Social Isolation Index in the country could have reflected in a 30.5% decrease in number of cases in 14 days. Adoption of physical distancing was associated with test coverage (IRR 0.976, 95% CI 0.973-0.979), home office (IRR 1.042, 95% CI 1.039-1.046), informal work proportion (IRR 0.961, 95% CI 0.958-0.965), political spectrum (IRR 0.961, 95% CI 0.958-0.965) and early moment of restrictive politics implementation (IRR 1.017, 95% CI 1.013-1.021). Physical distancing measures play a crucial role in mitigating the pandemic's spread. These analyses are crucial to support government decisions and improve the community's adherence to preventive measures.
