Correlation of sonographic and cytologic patterns of thyroid nodules.

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
introductionthyroid nodules are palpable in about 8% of adults. It is necessary to differentiate benign nodules from malignant ones by the non-invasive ultrasonography thereby reducing the frequency of the invasive fine needle aspiration cytology (FNAC). The study assessed the sonographic and FNAC patterns of thyroid nodules for benign and malignant features in a black African population.
methodsthis was a hospital-based, cross-sectional study design over a 1-year period in which one hundred and seven (107) consenting patients between 15 to 80 years of age with palpable thyroid masses by convenience sampling, were consecutively recruited to have both thyroid ultrasound scan and FNAC of their thyroid mass sequentially. Frequency, percentages and two-by-two contingency table were employed for data analysis.
resultsthe sonographic features of the thyroid nodules varied from round 80 (74.8%) to oval 25 (23.4%) masses, the presence of thin peripheral halo 83 (77.6%), heterogeneous echo-pattern 104 (97.2%) with cystic component and peripheral vascularity 75 (70.1%). One hundred and five (98.1%) study participants showed benign features on sonography while two had features suspicious of malignancy; however FNAC result in the same group of patients was suggestive of benign masses in all 107 (100%) patients. Histology however confirmed malignancy in the 2 participants with ultrasound features suggestive of malignant thyroid nodules.
conclusionultrasonography is very sensitive in the characterization of thyroid nodules into benign or suspicious for malignancy in black African population.
