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
introductionCognitive processing therapy (CPT) is widely regarded as a safe and effective first-line treatment for individuals with post-traumatic stress disorder (PTSD); however, no comparative studies have been conducted to examine the treatment outcomes in an Asian population. The aim of the present trial is to investigate the efficacy of CPT (individual format) as a treatment for PTSD in a population of Japanese patients. METHODS AND ANALYSIS: A 16-week, single-centre, assessor-masked, randomised, parallel-group superiority trial has been designed to compare the efficacy of CPT in conjunction with treatment as usual (mostly pharmacotherapy and clinical monitoring) versus treatment as usual alone. The Clinician-Administered PTSD Scale for the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) will be our primary outcome measure of the post-traumatic stress symptoms at 17 weeks, whereas the PTSD Checklist for DSM-5 and determination of the operationally defined responder status will be used to assess the secondary outcomes. An estimated sample size of 29 participants in each group will be required to detect an expected effect size of 1.4 (95% CI 0.85 to 1.95). ETHICS AND DISSEMINATION: The institutional review board at the National Center of Neurology and Psychiatry in Japan approved this study. The results of this clinical trial will be presented at conferences and disseminated through publication in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: UMIN000021670 (registered on 1 April 2016).
