The effects of differential injection sites of cold saline on transpulmonary thermodilution parameter values.
Article in Patient preference and adherence, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
aimTo investigate the effects of differential sites for cold saline injection on transpulmonary thermodilution parameter values.
methodsThis was a prospective study. Twelve patients were recruited for the following examinations: control condition (injection site at proximal injection end of the Swan-Ganz catheter), proximal end condition (injection site at sheath of the Swan-Ganz catheter), and distal end condition (injection site at PA end of the Swan-Ganz catheter). Sixty measurements were performed for each condition. The cardiac index, global end diastolic volume index (GEDI), and extravascular lung water index for the three different injection sites were recorded from each patient. In addition, the mean transmission time (MTt), downslope time, and area under the curve obtained from PiCCO-VoLEF-Win software were compared among different groups.
resultsThere were no differences in cardiac index and extravascular lung water index values among the three conditions (P>0.05). There were no differences in GEDI between the proximal end condition and control condition (P>0.05), while the GEDI was significantly lower for the distal end condition (493.33±254.65 mL/m(2)) than for the control condition (645.53±234.46 mL/m(2)) (P<0.05) and proximal end condition (717.96±321.63 mL/m(2)) (P<0.01). There were no differences in downslope time and area under the curve among the three conditions (P>0.05). There were no differences in MTt between the proximal end condition and control condition (P>0.05), while the MTt was significantly lower for distal end condition (40.22±16.37 seconds) than for the control condition (42.91±17.93 seconds) (P<0.05) and proximal end condition (47.16±16.64 seconds) (P<0.01).
conclusionThe differential sites for cold saline injection impacted transpulmonary thermodilution parameter values.
