Evaluation of testicular volume in males with congenital hypogonadotropic hypogonadism: a comparative analysis.

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
introductionEstimating accurate testicular volume (TV) of congenital hypogonadotropic hypogonadism (CHH) individuals is challenging due to the typically small testicular size. Ultrasound (USG) emerges as a vital solution, enabling precise measurements and reproducible results. The purpose of the study was to assess the three-dimensional measurement of the testis using USG and its volume was estimated using Ellipsoid (E) and Lambert (L) formulae and compared these with the TV by Prader orchidometer (OrTV).
methodsThis is an exploratory analysis of data taken from a clinical trial conducted from May 2022 to March 2024 which included 94 testes from 47 CHH participants. The OrTVs and USGTVs were assessed at baseline and every three months till the completion of the study making a total of 348 observations. The three-dimensional measurement of the testes was noted and TVs were calculated using the above formulae.
resultsThe mean age of the participants was 25.8 ± 6.14 years with a mean height of 169.9 ± 8.42 cm and body mass index (BMI) of 22.4 ± 4.72 kg/m
conclusionThe study revealed that all CHH patients at diagnosis had OrTV < 4 ml. This corresponds to a USG TV cut-off of 1.11 ml using the Ellipsoid formula and 1.51 ml with the Lambert formula, which could serve as a USG diagnostic criterion for CHH.
