The positive color Doppler sign post biopsy: effectiveness of US-directed compression in achieving hemostasis.
Article in Pediatric radiology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundPercutaneous biopsies of soft-tissue organs are frequently performed using US guidance. US permits visualization of blood flow on color Doppler imaging.
objectiveTo report the presence of color Doppler signal (positive color Doppler sign) along the biopsy tract after percutaneous needle biopsy of the liver and kidney as an indication of bleeding and to describe US-guided hemostasis. MATERIALS AND
methodsA case-control study of US-guided liver and kidney biopsies performed between January 2005 and September 2009 was undertaken. All pediatric patients with a positive color Doppler sign along the biopsy tract were included. Controls consisted of patients in whom no color Doppler sign was identified.
resultsFifty-three cases with positive color Doppler sign were identified. One hundred and six matched controls were selected. The average compression time was 9.2 min in kidney and 8.4 min in liver cases. US-guided compression achieved cessation of the positive color Doppler sign in all cases. There was no significant difference between the mean pre- and post-procedure hemoglobin and platelet levels between kidney cases and controls (P=0.68 and P=0.63, respectively) and between liver cases and controls (P=0.45 and P=0.80).
conclusionColor Doppler US can detect bleeding post percutaneous liver and kidney biopsies. US-guided compression is effective in obliterating the color Doppler signal and achieving appropriate hemostasis.
