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
backgroundPhlebotomy can be an uncomfortable and even painful experience that increases in likelihood in patients who require frequent blood draws, such as those with cancer. The 25-gauge BD Vacutainer® UltraTouch™ Push Button Blood Collection Set has a smaller outer bore needle size and unique bevel configuration, which in theory should reduce pain associated with phlebotomy. Smaller needles typically cause less pain, however, they have a higher incidence of compromising the specimen integrity. Innovative engineering allows this particular needle to maintain a larger inner bore size similar to a standard 23-gauge needle. This study compares pain and specimen integrity between this novel device and a standard 23-gauge needle.
methodsTwo cohorts of 190 patients each had phlebotomy performed with either needle. Pain experienced was assessed by patient surveys, rating pain from 0 (low) to 10 (high). Sample integrity was assessed by determining the hemolysis index (Abbott Architect c8000).
resultsNo statistically significant difference in median pain scores was observed between the 2 cohorts, P-value: 0.068. The 23-gauge cohort more frequently reported 3+ pain than the 25-gauge cohort, 14/190 vs 5/190. Pain scoring 1 and 2 was more frequent in the 25-gauge cohort, 84/190 vs 54/190. Pain scores of 0 were more frequent in the 23-gauge cohort, 122/190 vs 101/190. This stratification is statistically significant, P-value: 0.003. The 25-gauge needle showed no increase in hemolysis rates, P-value: 0.5.
conclusionsSample integrity was identical between both needles. The 25-gauge needle resulted in less 3+ pain, while pain scoring 1 and 2 was more frequent in the 25-gauge cohort.
