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
Non-steroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly prescribed drugs that can reduce pain. This study aimed to measure the concentration of piroxicam and celecoxib in Iranian hospitals, as well as the effect of electron beam irradiation on the degradation of these pollutants in synthetic and real samples. The high-performance liquid chromatography (HPLC) was used to detect the residual analytes in the samples. The Response Surface Methodology (RSM) was used to design the experiment conditions that investigate the effect of electron beam irradiation on degradation of piroxicam and celecoxib from synthetic samples, and then according to the optimum condition, the experiments were carried out for real wastewater samples. The results of wastewater analysis shown that the mean concentration of PIRO and CELE were 6.32 ± 2.5 and 11.5 ± 3.2 μg/L, respectively. Also, the findings show that 98.98 % and 97.62 % of piroxicam and celecoxib was degraded, respectively, when the optimum conditions (pH = 4, electron beam irradiation = 8 kGy, and concentrations of 60 μg/L for piroxicam and 50 μg/L for celecoxib) were applied. Results show that the degradation rates of piroxicam and celecoxib in the real wastewater sample at optimum condition were 89.6 % and 84.25 %, respectively. So, electron beam irradiation is a long-lasting and promising method for removal emerging contaminants from wastewater, like non-steroidal anti-inflammatory drugs, that can't be removed by conventional wastewater treatment methods; so, it can be used in combination with conventional wastewater treatment methods.
