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
Background Mini-percutaneous nephrolithotomy (mini-PCNL) has become a standard treatment for moderate-sized renal calculi. Among intracorporeal lithotripters, the thulium fiber laser (TFL), Holmium: YAG laser, and pneumatic devices remain the most widely used, yet direct comparative evidence in mini-PCNL remains limited. Aim The aim of this study is to compare the intraoperative efficiency, perioperative outcomes, and long-term sequelae of TFL, Holmium: YAG, and pneumatic lithotripters in mini-PCNL. Materials and methods A comparative study was conducted in 221 patients undergoing mini-PCNL for 10-30 mm renal stones. Patients were allocated to TFL (n=79), Holmium: YAG (n=72), or pneumatic lithotripter (n=70) groups. Demographics, stone characteristics, intraoperative parameters, perioperative complications, and 12-month outcomes were analyzed. Statistical comparisons included ANOVA and chi-square tests, with significance set at p<0.05. Results Baseline characteristics were comparable across groups. Stone disintegration time was significantly shorter in the TFL group (24.17 ± 4.7 min) than Holmium (31.45 ± 6.3) and pneumatic groups (35.26 ± 5.9) (p<0.01). Mean operative time was lowest with TFL (53 ± 9.8 min) versus Holmium (71 ± 14.6) and pneumatic (83 ± 12.8) (p<0.001) groups. In laser groups, energy usage per case was markedly lower with TFL (15.95 kJ) compared to Holmium (23.59 kJ) (p<0.01). Stone-free rate (SFR) was highest with TFL (94.8%), followed by Holmium (84%) and pneumatic (79%) (p=0.02) groups. TFL also showed the lowest hemoglobin drop (0.44 g/dL) and hematocrit change (3.2%, both p<0.05). Complication rates by Clavien-Dindo classification were similar, though hematuria and sepsis were more frequent in the pneumatic group. At 12 months, infundibular stenosis was detected in six TFL, four Holmium, and two pneumatic patients (p=0.18). Kaplan-Meier analysis demonstrated a nonsignificant trend toward higher stenosis with TFL. Conclusion TFL offers superior intraoperative efficiency, reduced energy usage, and a higher SFR in mini-PCNL. However, the potential for increased long-term stenosis requires further evaluation. Clinicians should weigh immediate benefits against possible delayed sequelae when selecting the lithotripter modality.
