Renal Ultrasonography Screening: A Comparison Between Male and Female Cohorts of University Students.

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
objectiveThis study aimed to assess renal ultrasonography findings in a cohort of university students. MATERIALS AND
methodsParticipants underwent renal ultrasonography screening in a prospective cross-sectional study using the Esaote MyLab40 system (Genoa, Italy). A 3.5-MHz transducer was used to evaluate the right (Rt) and left (Lt) kidneys for parenchymal texture and length measurements. Participants were selected using simple random sampling. Inclusion criteria consisted of asymptomatic university students. Descriptive statistics, t-tests, and Pearson correlation analyses were performed.
resultsA total of 100 participants with a mean age of 20.91 ± 1.52 years were enrolled. The mean kidney length was 9.68 ± 0.73 cm on the Rt side and 10.02 ± 1.19 cm on the Lt side. The mean body mass index (BMI) was 23.45 ± 5.24 kg/m². Incidental renal findings were observed in 5% of participants and were more frequent in males, including simple cysts (2%), renal agenesis (1%), and a double collecting system (2%). For males and females, respectively, the mean Rt kidney length was 9.9630 ± 0.56225 cm and 9.3904 ± 0.78268 cm, while the mean Lt kidney length was 9.9424 ± 1.58818 cm and 10.1046 ± 0.58872 cm. Females demonstrated slightly longer kidney lengths overall (t = 4.201,
conclusionIncidental renal sonographic findings were uncommon and occurred more frequently in males. Females demonstrated slightly longer kidney lengths. Kidney length showed a significant correlation with BMI.
