Utility of Society for Fetal Urology and Anteroposterior Pelvic Diameter Grading Systems for Estimating Time to Resolution of Isolated Hydronephrosis: A Single Center Study.
Observational study in The Journal of urology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
purposeWe aimed to compare the Society for Fetal Urology and anteroposterior pelvic diameter classification systems in predicting the time to resolution of isolated hydronephrosis. MATERIALS AND
methodsWe retrospectively reviewed isolated hydronephrosis cases prenatally detected and postnatally diagnosed between 1994 and 2018. Other urinary tract anomalies and vesicoureteral reflux were excluded. Baseline grades for both systems were collected. Anteroposterior pelvic diameter was classified as grade 1 to 4 over a scale of 5 mm. Resolution was defined by an anteroposterior pelvic diameter of less than 5 mm with Society for Fetal Urology grade I hydronephrosis. Time to resolution was analyzed using Kaplan-Meier curves.
resultsThe study population consisted of 831 patients (1,028 renal units). Median followup was 26 months (range 6 to 260), and 559 units (54.3%) reached resolution during a median followup of 9 months (1 to 133). Resolution rates at 48 months were 81.7%, 65.6%, 37.6% and 5.2% for Society for Fetal Urology grades I through IV disease and 80.0%, 41.2%, 13.1% and 2.5% for anteroposterior pelvic diameter grades 1 through 4, respectively. Discrepancies between these grades were present in 481 units (46.8%). Society for Fetal Urology grades II to IV categorized as anteroposterior pelvic diameter grade 1 showed a superior cumulative rate of resolution (84.7%) vs anteroposterior pelvic diameter grades 2 to 4 categorized as Society for Fetal Urology grade I (53.2%, log-rank test p <0.001).
conclusionsHydronephrosis cases with anteroposterior pelvic diameter grades 2 to 4 but categorized as Society for Fetal Urology grade I have an inferior cumulative rate of resolution than vice versa. Society for Fetal Urology grades have little influence on resolution when anteroposterior pelvic diameter is less than 10 mm. Therefore, anteroposterior pelvic diameter is more useful in predicting the time to resolution.
