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

The presence of off-odors can influence the overall taste of drinking water, with earthy-musty odors often being perceived as indicator of stale or poor-quality water. Recently, earthy-musty off-odor from drinking water was reported in some part of South Korea. The earthy-musty off-odor compound was identified as 2-methoxy-3,5-dimethylpyrazine (2-MDMP) through simultaneous steam distillation and solvent extraction-gas chromatography-mass spectrometry (SDE-GC-MS) and GC-olfactometry (GC-O). For quantitative analysis of 2-MDMP in drinking water, headspace-solid phase microextraction-GC-MS (HS-SPME-GC-MS) method was optimized in terms of salt concentration, absorption temperature, and absorption time. Validation of the method confirmed its reliability, with linearity (R
