Interformat reliability of the patient health questionnaire: Validation of the computerized version of the PHQ-9.
Article in Internet interventions, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 54 papers, 1 of them a synthesis that pooled it.
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
backgroundComputerized versions of well-established measurements such as the PHQ-9 are widely used, but data on the comparability of psychometric properties are scarce.
objectiveOur objective was to compare the interformat reliability of the paper-and-pen version with a computerized version of the PHQ-9 in a clinical sample.
methods130 participants with mental health disorders were recruited during psychotherapeutic treatment in a mental health clinic. In a crossover design, they all completed the PHQ-9 in both the computerized and paper-and-pen versions in randomized order.
resultsThe internal consistency was comparable for the computer (α = 0.88) and paper versions (α = 0.89), and highly significant correlations were found between the formats ( LIMITATIONS: In order to reduce the required effort for the participants, we did not ask them to fill out anything but the PHQ-9 once in paper and once in computer version.
conclusionsOur findings suggest that the PHQ-9 can be transferred to computerized use without affecting psychometric properties in a clinically meaningful way.
