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
backgroundMusculoskeletal (MSK) issues generate extensive use of diagnostic imaging. Geographical variations in imaging are of interest as they can indicate under- and overutilisation. Low-value imaging is defined as examinations where evidence suggests it confers no or very little benefit on patients. PURPOSE: To assess the temporal and geographical variations in MSK imaging with special attention to two potential low-value MSK examinations, i.e. MRI of knee and MRI of lower back, in Norway from 2013 to 2022. MATERIALS AND
methodsBoth inpatient and outpatient examinations from 2013 to 2022 were included. Data on outpatients was collected from the Norwegian Health Economics Administration, while inpatient data was gathered directly from strategically selected hospitals in Norway. Missing inpatient data was extrapolated based on population and outpatient data for each hospital trust. The rates are adjusted for age and sex to the European Standard Population.
resultsYearly, 1,884,614 MSK examinations were conducted in Norway. I.e. 3,586 examinations per 10,000 inhabitants. The use of MSK imaging decreased by 6.8% during the study period. The geographical variations were highest for the use of the potential low-value MSK examinations, where the region with the highest use conducted over twice as many examinations than the region with the lowest use.
conclusionThe temporal variations in the use of MSK examinations was small. However, there were substantial geographical variations between the hospital trusts, and modest variations between the regional health trusts. Reducing low-value examinations could free up resources for examinations with high value.
