Validity and Performance of the Patient Health Questionnaire (PHQ-2) for Screening of Depression in a Rural Chilean Cohort.
Article in Community mental health journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
Validity of PHQ-2 to screen for depression was assessed in an agricultural population in Chile. The sample included 4767 adults enrolled from 2014 to 2017 in a population-based cohort of chronic disease in Maule, Chile. Receiver operating characteristic (ROC) curve analysis was used to find the optimal PHQ-2 cut-off for depression, defined as the highest Youden index, using PHQ-9 as a reference standard. Sensitivity, specificity, and Youden J index were calculated for every cut-off point of PHQ-2. Prevalence of depression measured by PHQ-9 and PHQ-2 was 18% and 18.4%, respectively. Corresponding rates for women were 24.7% and 23.6%, and 8.3% and 10.9 for men. The optimal PHQ-2 cut-off score was 3, achieved with a sensitivity of 74.6%, specificity 93.9%, and Youden index of 0.68. The area under the curve for the ROC analysis ROC curve was 0.92 (95% CI 0.91-0.93). PHQ-2 has good performance for use as a test for depression screening in a rural population of Chile and can be easily applied in areas with low resources.
