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
Based on the regulations of the Ministry of Health and Welfare (MOHW) of Taiwan in 2017, an analysis of 373 pesticides in food was conducted using the MOHW official method. The analyses involved the use of either liquid chromatography mass spectrometry (LC-MS) with electrospray ionization (ESI) or gas chromatography mass spectrometry (GC-MS) with electron ionization (EI). In this study, the applicability of detecting pesticides using atmospheric pressure chemical ionization (APCI) was investigated and evaluated. The pesticides were separated using an aqueous solution of ammonium formate with methanol as the mobile phase, and ionization efficiency was compared between APCI, ESI, and EI coupled with triple quadrupole mass spectrometer using multiple reaction monitoring (MRM) acquisition. Among the 196 pesticides that were originally analyzed by ESI, 164 could be successfully detected by APCI with 6 showing a higher sensitivity when APCI was used. Among the 177 pesticides that were analyzed by EI, 43 could be successfully detected by APCI. The results also showed that APCI gave superior ionization efficiency for pesticides containing triazine, imidazole, triazole, and pyrazole groups.
