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
backgroundAspiration cytology is one of the first-line diagnostic tests in thyroid malignancies. Fine-needle aspiration cytology (FNAC) in thyroid lesions causes hemorrhagic smear and cell trauma, often leading to the repetition of smear and delay in diagnosis. This study was conducted to identify the diagnostically superior technique with regard to thyroid swelling and to assess the quality of smears obtained from FNAC and fine-needle nonaspiration cytology (FNNAC). METHODOLOGY: This was a prospective diagnostic study carried out for 2 years in a tertiary care center from South India. All patients with complaints of thyroid swellings, after examination, underwent FNNAC, followed by FNAC of the lesion. They underwent thyroidectomy when indicated. The final postoperative biopsy reports were compared with the preoperative reports of these two techniques (FNNAC and FNAC). The quality of smears was compared using Mair's score.
resultsThe sensitivity, specificity, positive predictive value, negative predictive value, and accuracy in diagnosing malignancy were 93.4%, 100%, 100%, 98.78%, and 98.96% for FNNAC and 94.12%, 100%, 100%, 98.82%, and 99% for FNAC, respectively, which were comparable. Regarding the quality of smears, FNNAC had more smears with less blood in the background. FNAC had more smears with adequate cellularity. The difference in overall Mair's score between the two techniques was not significant (
conclusionNo difference was found in the accuracy of FNAC and FNNAC in diagnosing thyroid lesions. Furthermore, the smear quality of both techniques was comparable. Hence, either can be used based on the operator's preference and experience.
