The Assessment of Cough in a Sarcoidosis Clinic Using a Validated instrument and a Visual Analog Scale.
Article in Lung, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 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
purposeCough is a common symptom of pulmonary sarcoidosis. We analyzed the severity of cough and factors associated with cough in a university sarcoidosis clinic cohort.
methodsConsecutive patients completed the Leicester Cough Questionnaire (LCQ) and a cough visual analog scale (VAS). Clinical and demographic data were collected. Means of the LCQ were analyzed in patients who had multiple visits in terms of constant variables (e.g., race, sex).
results355 patients completed the LCQ and VAS at 874 visits. Cough was significantly worse in blacks than whites as determined by the LCQ-mean (16.5 ± 2.6 vs. 17.8 ± 3.0, p < 0.001) and VAS-mean (3.8 ± 3.0 vs. 2.0 ± 2.6, p < 0.0001). Cough was worse in women than men as measured by the VAS-mean (2.7 ± 2.9 vs. 2.2 ± 2.7, p = 0.002), one of the LCQ-mean domains (LCQ-Social-mean 5.4 ± 0.9 vs. 5.2 ± 1.0, p = 0.03), but not the total LCQ-mean score. Cough was not significantly different by either measure in terms of smoking status, age, or spirometric parameter (FVC % predicted, FEV1 % predicted, FEV1/FVC). In a multivariable linear regression analysis, cough was significantly worse in blacks than whites and in pulmonary sarcoidosis than non-pulmonary sarcoidosis with both cough measures, in women than men for the VAS only, and not for spirometric parameters, Scadding stage, or age. The LCQ and VAS were strongly correlated.
conclusionsIn a large university outpatient sarcoidosis cohort, cough was worse in blacks than whites. Cough was not statistically significantly different in terms of age, spirometric measures, Scadding stage, or smoking status. The LCQ correlated strongly with a visual analog scale for cough.
