Tolerability and pharmacokinetics of disodium folinate following single intravenous doses in healthy Chinese subjects: an open-label, randomized, single-center study.
Trial report in European journal of drug metabolism and pharmacokinetics, 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
The tolerability and pharmacokinetics of disodium folinate may vary with different races, and these variations might result in different outcomes. This study assessed the tolerability and pharmacokinetics of disodium folinate following single intravenous doses in healthy Chinese subjects, with gender factor also taken into account. Subjects were randomized to receive a single dose of disodium folinate at 20, 200, or 300 mg/m(2) administered intravenously over a time period of 10 min. Sequential blood samples were collected at regular intervals over 24 h after dosing and were analyzed using a validated high-performance liquid chromatography (HPLC) method. Pharmacokinetic parameters, including C max, AUC0-t, t 1/2, V d, and CL, were calculated using non-compartmental models. Tolerability was assessed by collecting adverse events (AEs) and monitoring vital signs, physical examinations, laboratory tests, and electrocardiograms. Following a single intravenous administration of disodium folinate 20, 200, and 300 mg/m(2), the mean (standard deviation) pharmacokinetic parameters were as follows: C max = 5.18 (0.58), 47.80 (10.10), and 69.93 (9.72) µg/mL; AUC0-t = 25.85 (3.36), 194.53 (30.18), and 355.26 (35.31) µg h/mL; AUC0-∞ = 30.24 (6.19), 215.43 (27.34), and 417.88 (54.81) µg h/mL; t 1/2 = 8.77 (2.57), 7.64 (1.81), and 9.08 (1.64) h; CL = 1.12 (0.18), 1.55(0.25), and 0.78 (0.09) L/h; V d = 13.75 (2.61), 17.38 (6.44), and 10.05 (1.49) L, respectively. The mean C max, AUC0-t, and AUC0-∞ increased in a dose-proportional manner. No significant differences in pharmacokinetic parameters were noted by gender. The most common AEs reported were mild redness at the injection site and neurological symptoms (headache, dizziness, and fatigue).
