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
backgroundFlexible bronchoscopy is the diagnostic tool of choice to diagnose endobronchial lesions. Pathological samples can be harvested using various techniques, for example, forceps biopsy, brushing, washing, and recently cryobiopsy. The major drawbacks of forceps biopsy technique are (a) obtaining of smaller tissues and (b) presence of crush artefacts. This results in a significant failure rate. Cryobiopsy is the procedure where application of extreme cold to the pathological tissues is used for obtaining samples. As a cryoprobe allows procurement of larger biopsy samples which is devoid of any crush artefacts, these result in better histopathology, immunohistochemistry, and identification of specific genetic mutations.
methodsThe current trial tried to assess (i) the diagnostic yield of endobronchial cryobiopsies in comparison with endobronchial forceps biopsies and (ii) assess the duration of procedures and requirement of interventions to control bleeding, among 49 patients who had undergone forceps biopsy and 48 patients who had undergone cryobiopsy. The types of endobronchial lesions observed during bronchoscopic procedures were divided into (a) exophytic type and (b) infiltrative type. Biopsy interpretations were done by an expert pathologist.
resultsCryobiopsy compared to forceps biopsy had a statistically significant higher diagnostic yield for diagnosis of overall endobronchial lesions (P < 0.0001) for both exophytic (P = 0.015) and infiltrative (P < 0.0001) growth. Cryobiopsy obtained larger tissue (P < 0.001). No statistically significant difference was found in the incidence of haemorrhage (P = 0.378) and duration (P = 0.173) between two procedures.
conclusionsCryobiopsies were more successful than forceps biopsies particularly for diagnosis of infiltrative growth. The complication rate was similar between the two procedures.
