Does the contralateral testicular volume decide the need for diagnostic laparoscopy in cases of unilateral impalpable undescended testis?
Trial report in BMC urology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05933811 (Does the Contralateral Testicular Volume Decide the Need for Diagnostic Laparoscopy in Cases of Unilateral Impalpable Undescended Testis?), which is not on this map.

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.

Abstract
backgroundThis study aimed the evaluation of the value of the calculated volume of a normal testis to predict the status of its contralateral impalpable side and hence decide the importance of laparoscopic exploration.
methodsPatients with unilateral impalpable undescended testis - as confirmed by clinical and sonographic examination- were enrolled in our prospective interventional study between November 2018 and August 2022 at Elshatby University Hospital, Faculty of Medicine, Alexandria University. The volume and three-dimensional diameter of the normal contralateral testis were measured by the pre-operative US using the formula: Volume = L x W x H x π/6, where L is the length, W is the width, H is the height, and was correlated with the intra-operative laparoscopic findings.
resultsSeventy-six patients were included in our study. The age of the studied patients ranged between 6 months and 4 years with a mean of 2.17 ± 1.30 years; most of them were between one and three years old. Forty-six patients (60.5%) have left-sided impalpable testis and 30 patients (39.5%) have right-sided impalpable testis. The calculated volume of the contralateral normal testis was significantly larger in those patients who had both blind ending vas and vessels (0.89 ± 0.16) and in those who had an atrophic testis passing through the deep inguinal ring (DIR) -which was excised through the inguinal region- (0.83 ± 0.20) than in those patients who had their testes intra-abdominal (0.53 ± 0.18) or passing through the DIR to the inguinal region (0.80 ± 0.19). (Kruskal Wallis test; p < 0.001*).
conclusionsThe calculated sonographic volume of a normal testis can predict the status of its contralateral impalpable side significantly with sensitivity & specificity of 75.0% & 88.89% respectively and a cut-off point of ≤ 0.674; hence, helps in parent counselling preoperatively.
