High-dose continuous venous infusion of interleukin-2: influence of dose and infusion rate on tumoricidal function and lymphocyte subsets.
Trial report in Cancer immunology, immunotherapy : CII, 1995. 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
Previous clinical studies have demonstrated a dose-response relationship between enhancement of certain immune parameters and interleukin-2 (IL-2) dose in trials with low dosages of the cytokine. This has not been demonstrated for high-dose (greater than 18 x 10(6) IU/m2 per day) IL-2. We completed phase II trials of sustained administration of indomethacin and ranitidine with IL-2 given as a continuous infusion over 5 days for three courses. Peripheral blood mononuclear cells, both fresh and cultured in vitro with IL-2 or IL-2 and indomethacin, were tested for tumoricidal function against K562 and Daudi targets; these results were then correlated with actual delivered dose and mean infusion rate per course. Similar correlations were calculated between delivered dose or infusion rate and absolute and proportional counts of lymphocyte subsets as determined by flow cytometry. No enhancement of in vitro tumoricidal function with either increasing delivered dose or increasing infusion rate was seen. No consistent pattern of correlation was found between the absolute counts of lymphocyte subsets after each course of IL-2 with delivered dose or infusion rate. The percent rise in absolute counts of selected T- and NK-cell subsets at the end of course 1 compared with baseline values correlated positively with infusion rate; however, a similar correlated between the infusion rate and an increase in lymphocyte tumoricidal function was lacking. Little evidence was found for improved tumoricidal function of mononuclear cells or consistent enhancement of lymphocyte subset counts in patients able to tolerate doses of IL-2 beyond 18 x 10(6) IU/m2 per day in a 5-day continuous infusion schedule.
