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
introductionbreast lump is the commonest presentation for both benign and maligant breast conditions. Both ultrasound guided and conventional fine needle aspiration cytology (FNAC) have been used for diagnosing of breast malignancy among patients with palpable breast lumps. This study compared diagnostic utility of ultrasound guided versus conventional FNAC in diagnosing breast malignancies among patients with palpable breast lumps at Bugando Medical Centre.
methodsthis was a hospital based cross sectional study with a follow up component that combined both retrospective data (from January 2017 to June 2018) and prospective data (from July 2018 to June 2019).
resultsduring the study, total of 354 patients (male; female = 1: 32) were enrolled in the study. A total of 134 (37.9%) patients had malignant lesions while 220 (62.1%) of patients had benign lesions confirmed on histology. The diagnostic utility (sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy) for conventional FNAC was 86.7%, 95.7%, 93.5%, 91.1% and 92.0% with an 8% error margin versus ultrasound guided FNAC all were 100% with a 0% error margin respectively.
conclusionboth ultrasound guided and conventional FNAC show almost perfect agreement with histology. However, ultrasound guided FNAC has a higher diagnostic utility relative to conventional FNAC in diagnosing breast malignancies.
