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

Landfill gas condensate (LFGC) is an underused byproduct that could reduce the cost and environmental impact of purchased external carbon for biological nitrogen removal. This study tested LFGC as a denitrification carbon source in sequencing batch reactors (SBRs) co-treating municipal sewage and landfill leachate. Four lab-scale SBRs operated for 170 days with 98.5% sewage and 1.5% landfill leachate, supplemented with methanol, glycerin, sodium acetate, or LFGC. All reactors performed stably, achieving total nitrogen removal efficiencies of 93.1%-93.8% and effluent nitrate below 1 mg N/L. The LFGC reactor reached nitrate removal up to 99.2%, with effluent NO
