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.
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
Regarding the increasing trend of methamphetamine consumption in society, identifying and measuring low levels of methamphetamine in biological matrices is of great importance for clinical and forensic laboratories. Coated ionic liquid silica nanoparticles (CILSNPs) are appropriate adsorbent candidates to extract methamphetamine with high selectivity and sensitivity from complex urine matrix using the mixed hemimicelle dispersive solid-phase extraction (MHMDSPE) method. After successful characterization of synthesized CILSNPs by various techniques such as FTIR, XRD, SEM, and Zeta potential, the one-factor-at-a-time (OFAT) method was performed to optimize effective extraction parameters. HPLC-UV method was used to detect and quantify methamphetamines. The optimized extraction parameters were as follows: 400 µL of methanol, 10 min of extraction, 5 min of desorption time, stirring rate of 2,000 rpm, urine pH of 10, 40 mg of adsorbent, and 10 mL of urine volume. The calibration curve was plotted in the 50-2000 ng/mL concentration range, and the method was validated. The method's limit of detection (LOD) was calculated as 9 ng/mL. Analysis of addicted subjects for the proposed method proves that the method could be used in clinical and analytical laboratories to detect methamphetamine efficiently.
