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
objectiveTo analyze the risk factors associated with failure of minimally invasive parathyroidectomy (MIP) in patients with primary hyperparathyroidism (PHPT). MATERIALS AND
methodsA retrospective analysis was performed using a prospectively collected database of patients diagnosed with primary hyperparathyroidism who underwent MIP between December 2006 and November 2025. Demographic, intraoperative, and postoperative variables were analyzed. Logistic regression analysis was performed to identify risk factors associated with failures in MIP, which included conversion to bilateral neck exploration (BNE), disease persistence (DP), and disease recurrence (DR).
resultsA total of 497 patients underwent MIP; 427 (85.9%) were women, with a mean age of 59.8 years (range: 22-93 years). Fifty-nine patients (11.9%) required conversion to BNE. A gland weight greater than 300 mg and discordant preoperative imaging studies were independently associated with conversion to BNE in both univariable and multivariable analyses. Postoperatively, 13 patients (2.6%) presented with DP, and a significant association was found between this failure and age over 70 years (p < 0.05). Recurrent disease occurred in only 3 patients (0.6%). Obesity, a gland weight greater than 300 mg and discordant imaging studies showed an association with DR in the univariable analysis; however, these findings should be interpreted cautiously given the low number of recurrence events.
conclusionPatients with over 70 years, those without preoperative matching studies, and/or those with gland weight exceeding 300 mg should be informed about the increased risk of failure of MIP. Appropriate patient selection is essential to minimize the risk of MIP failure. LEVEL OF EVIDENCE: 3:
