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
Worldwide, there are an insufficient number of primary care physicians to provide accessible, high-quality primary care services. Better knowledge on the health impacts of policies aimed at improving access to primary care physicians is important for informing future policies. Using a generalised synthetic control estimator (GSC), we estimate the effect of the increase in primary care physicians from the Programa Mais Médicos in Brazil. The GSC allows us to estimates a continuous treatment effects which are heterogenous by region. We exploit the variation in physicians allocated to each Brazilian microregion to identify the impact of an increasing Mais Médicos primary care physicians. We explore hospitalisations and mortality rates (both total and from ambulatory care sensitive conditions) as outcomes. Our analysis differs from previous work by estimating the impact of the increase in physician numbers, as opposed to the overall impact of programme participation. We examine the impact on hospitalisations and mortality rates and employ a panel dataset with monthly observations of all Brazilian microregion over the period 2008-2017. We find limited effects of an increase in primary care physicians impacting health outcomes - with no significant impact of the Programa Mais Médicos on hospitalisations or mortality rates. Potential explanations include substitution of other health professionals, impacts materialising over the longer-term, and poor within-region allocation of Mais Médicos physicians.
