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

We describe a method to determine the nitrogen and oxygen isotopic composition of nitrate in groundwater samples ((15)N/(14)N and (18)O/(16)O, respectively), which is based on the analysis of nitrous oxide gas (N2O) that is produced quantitatively from nitrate by denitrifying bacteria. This method which is simple, inexpensive and effective in the removal of nitrite is greatly selective for NO2(-) and was used for mixed samples containing both NO2(-) and NO3(-) with little or no measurable cross-contamination. The precision of δ(15)N and δ(18)O are 0.3 and 0.17‰ respectively, compared to that of 0.1 and 0.5‰ abroad (Brand et al. in Org Geochem 21:585-594, 1994; Begley and Scrimgeour in Anal Chem 69(8): 1530-1535, 1997; Kornexl et al. in Rapid Commun Mass Spectrom 13(16):1685-1693, 1999; Böhlke et al. in Rapid Commun Mass Spectrom 17:1835-1846, 2003; Gehre and Strauch in Rapid Commun Mass Spectrom 17(13):1497-1503, 2003; Werner in Isot Environ Health Stud 39:85-104, 2003).
