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
introductionOur aim was to assess how monoplanar fluoroscopy-guided access affects the outcomes of percutaneous nephrolithotomy (PCNL).
methodsThis retrospective study included all patients who had renal stones and underwent prone PCNL using monoplanar fluoroscopy-guided access in a single tertiary care center between January 2015 and January 2024. Preoperative and postoperative patient- and procedure-related variables, such as operative time, intraoperative blood loss, number of tracts, complications, stone-free rate (SFR), and hospital stay, were assessed. Multivariable analysis was performed to detect predictors of residual stones and complications.
resultsA total of 662 patients with an average age of 47±12 years were included. Comorbidities were reported in 26.1%. American Society of Anesthesiologists (ASA) score was I in 64.8%. The mean stone diameter was 2.8±0.9 cm. Only 6% had positive preoperative urine culture. The mean stone Hounsfield unit (HU) was 1054±304 with a mean operative time of 94±31 minutes. Most cases (74.9%) required only one tract. Postoperative fever was reported in 22.4%. The median estimated blood loss (EBL) was 160 mL. The complications included urine leak (4.1%), blood transfusion (1.5%), sepsis (1.5%), renal pelvic perforation (0.8%), superselective angio-embolization (0.6%), pleural injury (0.6%), and colonic injury (0.2%). The median hospital stay was three days. Approximately 73% were stone-free. The only predictor of residual stone was higher stone diameter (odds ratio [OR] 1.536, p=0.001). Predictors of complications were three tracts (OR 4.501, p=0.033) and higher EBL (OR 1.003, p<0.001).
conclusionsThe monoplanar fluoroscopy-guided approach has demonstrated a noteworthy success rate, rendering it a safe modality for prone conventional PCNL.
