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
Aetiology of acquired laryngotracheal stenosis (ALTS) is complex and heterogenous. The aim of this study is to discuss the role of primary aetiology of intubation in the development and outcomes of Post intubation Laryngo tracheal stenosis (PILTS). A retrospective review of patients diagnosed and managed as PILTS from May 2008 to January 2017 was conducted. Demography, primary aetiology of intubation, grade of stenosis, length of the stenotic segment, treatment and outcomes of these patients were recorded and analysed. Based on aetiology of intubation, patients were divided into Poisoning (I), Neurogenic (II) and Rest of aetiologies (III) group respectively. Group I had 28/52 patients (53.8%) followed by group II, 15/52(28.8%) and group III, 9/52(17.3%) respectively. Organophosphorus compound poisoning (OPP) (44.2%) was the commonest cause overall followed by Brain injury (23.1%) and Acute Respiratory Distress Syndrome (ARDS) (11.5%). Trachea (46.15%) was the commonest subsite involved in this study. 24/28(85.7%) of patients had advanced (either grade 3 or 4) subglottic stenosis. The average length of stenotic segment in the study was 18.5 ± 9.2 mm (7-34 mm). 39/52(74.9%) of patients underwent open surgical approaches like cricotracheal resection and anastomosis, Laryngotracheal reconstruction or Shian-Yan Lee technique. 48/52(92.3%) patients were decannulated successfully. There was no significant association between primary etiology of intubation and outcomes. We conclude that OPP and neurological disease patients are more susceptible to airway injury. The authors emphasize that clinicians should be aware of these facts and manage these susceptible patients accordingly.
