Psychometric validation and interpretation of the Nocturia Impact Diary in a clinical trial setting.
Trial report in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03201419 (A Randomised, Double-blind, Placebo-controlled, Response-adaptive Dose-finding Trial Investigating the Efficacy, Safety and Tolerability of Oral Doses of FE 201836, With Desmopressin Orally Disintegrating Tablet as a Benchmark, During 12 Weeks of Treatment for Nocturia Due to Nocturnal Polyuria in Adults), which is not on this map.

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.

Abstract
purposePsychometric evaluation of the Nocturia Impact (NI) Diary was conducted to support its use as a trial endpoint.
methodsAs part of a randomized, controlled Phase 2 clinical trial investigating a novel drug candidate for nocturnal polyuria, adult nocturia patients completed the NI Diary and a voiding diary for three nights preceding their clinic visit at Baseline and Weeks 1, 4, 8, and 12 (end of treatment). Exit interviews were conducted to obtain patient impressions of the NI Diary.
resultsA total of N = 302 participants were included. Confirmatory factor analysis (CFA) indicated that the 11-item measure is unidimensional with values of CFI, TLI, and RMSEA meeting relevant thresholds. Good internal consistency (Cronbach's α 0.941) and test-retest reliability (intra-class correlation coefficients 0.730-0.880). Convergent validity with two reference measures was demonstrated with strong correlations of 0.573-0.730 were shown. Significant differences (P = 0.0018, standardized effect size = 0.372) between groups defined by number of night-time voids supported known-groups validity. Exit interviews in 66 patients indicated all participants experienced improvement in at least 1 NI Diary item and that a 1-point improvement on the item response scale and 1-void reduction per night (associated with an average best cut point on ROC analysis of - 11.6) constituted meaningful improvement. Anchor and distribution-based analyses identified a meaningful change threshold of - 15 to - 18 points on the NI Diary.
conclusionThe NI Diary is a reliable and valid patient-reported psychometric instrument which is fit-for-purpose to evaluate the impact of nocturia on patient quality of life in the clinical trial setting. Trial registration number and registration date NCT03201419; June 28, 2017.
