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: Typical pulmonary carcinoid tumors are uncommon, well-differentiated neuroendocrine neoplasms that often arise in the central airways and may present with nonspecific obstruction-related respiratory symptoms, resulting in delayed diagnosis. We report a three-case series of endobronchial typical pulmonary carcinoid tumors in young adults, highlighting their variable obstructive complications and surgical outcomes. Methods: This retrospective case series included three consecutive patients managed at a tertiary university hospital in Syria. Clinical presentation, imaging, bronchoscopic findings, operative details, histopathology, and follow-up data were obtained from medical records. All patients had histopathologically confirmed typical pulmonary carcinoid tumors with central/endobronchial involvement and underwent definitive surgical resection. Patient identifiers were removed, and written informed consent for publication and use of accompanying images was obtained. Results: The patients were 23-35 years old and presented with different manifestations of central airway obstruction: chronic productive cough (Case 1), post-obstructive suppuration with lung abscesses (Case 2), and recurrent hemoptysis with atelectatic/post-obstructive changes (Case 3). Bronchoscopy demonstrated obstructing endobronchial lesions in all three cases, and histopathology confirmed typical carcinoid tumors with low mitotic activity and no necrosis. Case 1 underwent right middle and lower bilobectomy with systematic mediastinal lymph node dissection for a large tumor staged T4N1M0. Cases 2 and 3 underwent left lower lobectomy; in Case 3, this included bronchial segment resection with primary closure and mediastinal lymph node dissection. Resection margins were negative in all cases, and mediastinal nodes were negative in Cases 2 and 3. No adjuvant therapy was administered. Follow-up showed no recurrence approximately 4.5 years after surgery in Case 1, clinical stability at one month in Case 2, and stable chest imaging at six months in Case 3. Conclusion: Endobronchial typical pulmonary carcinoid tumors in young adults can produce diverse obstruction-related complications, including chronic cough, post-obstructive suppuration, and hemoptysis with atelectatic changes. Timely airway evaluation and complete surgical resection with appropriate nodal assessment can achieve favorable outcomes, including in locally advanced disease when complete resection is feasible.
