1 · What the graph read from 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.

2 · The registry

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

backgroundUntil now there has been no study that directly compares the effect of lansoprazole and pantoprazole administered intravenously on intragastric acidity. The aim of this study is to compare the effect of lansoprazole (30 mg) and pantoprazole (40 mg) administered intravenously on gastric acidity. MATERIAL/

methodsHelicobacter pylori-negative healthy volunteers were recruited in this open-label, randomized, two-way crossover, single centre study. Lansoprazole at 30 mg or pantoprazole at 40 mg was intravenously administered twice daily for 5 consecutive days with at least a 14-day washout interval. Twenty-four-hour intragastric pH was continuously monitored on days 1 and 5 of each dosing period.

resultsTwenty-five volunteers completed the 2 dosing periods. The mean intragastric pH values were higher in subjects treated with lansoprazole than those with pantoprazole on both day 1 (6.41 ± 0.14 vs. 5.49 ± 0.13, P=0.0003) and day 5 (7.09 ± 0.07 vs. 6.64 ± 0.07, P=0.0002). Significantly higher percentages of time with intragastric pH >4 and pH >6 were found in the subjects treated with lansoprazole than those with pantoprazole on day 1 (pH >4, 87.12 ± 4.55% vs. 62.28 ± 4.15%, P=0.0012; pH >6, 62.12 ± 4.12% vs. 47.25 ± 3.76%, P=0.0216) and pH >6 on day 5 (76.79 ± 3.77% vs. 58.20 ± 3.77%, P=0.0025).

conclusionsIntravenous lansoprazole produces a longer and more potent inhibitory effect on intragastric acidity than does intravenous pantoprazole.
