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
Background: Approximately 15% of fine-needle aspiration biopsy (FNAB) procedures are considered inconclusive, caused by various factors such as nodule characteristics, level of expertise, and needle size. Since needle size may play a crucial role in both adequacy of FNAB samples and reduction of complications, our objective was to compare cytology specimen adequacy, blood contamination, and findings in thyroid nodules and lymph nodes using 22- and 25-gauge needles in fine-needle aspiration (FNA). Materials and methods: A retrospective comparative cohort study was conducted at King Fahad Specialist Hospital, Saudi Arabia. Data were collected from electronic medical records between January and December 2021. An ultrasound-guided FNA procedure was performed. Each nodule was sampled in three passes using a 25-gauge and a 22-gauge fine needle. A total of 153 (115 with thyroid nodules; 57 with 22-gauge and 58 with 25-gauge and 38 with lymph nodes; 21 with 22-gauge and 17 with 25-gauge) cases were included. Data analysis was done using SPSS version 26. All cases were divided into two groups: 22-gauge or 25-gauge needle group. Chi-square test and binary logistic regression were used for comparison. Results: No significant differences were found. Adequacy rates were 93.9% for thyroid and 97.4% for lymph node samples ( Conclusion: The study highlights the importance of the number of passes during the procedure, with a higher number of passes associated with decreased odds of obtaining an adequate sample. The needle size does not significantly impact the various variables assessed.
