1 · What the graph read from it

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.

2 · The registry

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

backgroundWe aimed to determine a data-based annual hospital volume threshold for transurethral resection of the prostate (TURP), simple prostatectomy, holmium laser enucleation of the prostate (HoLEP), and thulium laser enucleation of the prostate (ThuLEP) and evaluate its clinical significance regarding perioperative morbidity. MATERIALS AND

methodsWe utilized the German Nationwide Inpatient Data (GRAND), provided by the Research Data Center of the Federal Statistical Office (2005-2022). Based on ROC analyses, the optimal annual hospital volume threshold to reduce perioperative incontinence, intensive care unit (ICU) admission, sepsis, transfusion, and hospital stay was identified for these surgeries.

resultsA total of 1,084,650 TURP cases, 90,735 simple prostatectomy cases, 64,325 HoLEP cases, and 15,241 ThuLEP cases were included. For TURP, the annual hospital volume threshold to reduce perioperative morbidity was 266 cases for incontinence, 196 for ICU admission, 279 for sepsis, 241 for transfusions, and 139 for hospital stay. For simple prostatectomy, the annual hospital volume threshold to reduce perioperative morbidity was 22 cases for incontinence, 11 for ICU admission, 26 for sepsis, 23 for transfusions, and 32 for hospital stay. For HoLEP, the annual hospital volume threshold to reduce perioperative morbidity was 290 cases for incontinence, 120 for ICU admission, 140 for sepsis, 132 for transfusions, and 180 for hospital stay. For ThuLEP, the annual hospital volume threshold to reduce perioperative morbidity was 55 cases for incontinence, 56 for ICU admission, 217 for sepsis, 331 for transfusions, and 68 for hospital stay.

conclusionThe annual hospital volume threshold for improving perioperative outcomes in BPH surgery is high. Thus, centralization of benign prostatic hyperplasia surgery may be mandatory in some cases.
