Laboratory test use and primary care physician supply.
Article in Canadian family physician Medecin de famille canadien, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
objectiveTo determine the relative effects of population size, FP and GP supply, and other specialist supply on chemistry and hematology test volumes (ie, number of tests performed).
designPopulation-level analysis using secondary data from the Calgary Health Zone for 2004 to 2009.
settingCalgary, Alta.
main outcome measuresThe relative effects of population size, FP and GP supply, and other specialist supply on laboratory test use.
resultsPopulation size was the strongest predictor of test volumes in a multivariate analysis. The FP and GP supply was significantly negatively correlated with chemistry test volume (partial r(2) = 0.186, P = .045). There was a trend toward decreasing use of hematology tests with increasing FP and GP supply (partial r(2) = 0.117, P = .119).
conclusionThe relationship between FP and GP supply and laboratory test use is complex, but increasing numbers of FPs do not necessarily indicate an increase in laboratory test use and might be associated with a decrease in test use when other factors are controlled for.
