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

Drug abuse is a substantial problem worldwide, with a prevalence of >2% in Southeast Asia. However, the detection of illegal drugs in urine is time-consuming and requires expert interpretation. Therefore, this study aimed to establish attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy and machine learning algorithms to screen and analyze urine samples of narcotic drug users for methamphetamines and tetrahydrocannabinol. Urine supernatant samples provided clearer absorption peaks compared to the whole urine samples, allowing for better discrimination between nondrug users and drug users. Principal component analysis revealed key spectral regions (3500-3000 cm
