1 · What the graph read from it

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.

2 · The registry

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

objectiveTo identify cytologic characteristics in a suspicious for malignancy cohort that may help to recognize false positives in cytopathological tests of thyroid nodules in a "real world scenario", with histopathological reports as the gold standard.

methodsCytomorphologic features of suspicious for malignancy thyroid nodules in a 13-year retrospective database were reviewed. Therefore, we identified false positive cases, analyzed the possible causes of cytopathological diagnostic failure and calculated the frequency of false positive results and the risk of malignancy in the suspicious for malignancy cohort.

resultsAmong the 289 suspicious for malignancy type nodules, 283 were malignant, 5 were benign, and 1 was a noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). The most frequently reported cytology features were nuclear grooves and pseudoinclusions; however, they were present in malignant and benign specimens. Statistical analysis revealed that the presence of micronucleoli (p < 0.001) and/or irregular/oval nuclei (p = 0.05) were the characteristics most strongly associated with malignancy. The risk of malignancy was 98% in this study.

conclusionThe presence of micronucleoli and nuclear irregularity was highly predictive of malignancy according to suspicious for malignancy cytology and were not present in false positive patients. Hence, careful examination of nuclear characteristics can be helpful for identifying true malignancies via suspicious for malignancy cytology. This was significant even when only a qualitative analysis was taken into account.
