1 · What the graph read from 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.

2 · The registry

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

purposeTo translate and culturally adapt the Core Outcome Measures Index for the back (COMI-back) into Thai and to evaluate its psychometric properties in Thai-speaking patients with low back pain (LBP).

methodsThe translation process followed a standardized forward-backward method with two independent translators, followed by synthesis and back-translation. An expert committee reviewed the translations for cultural and conceptual equivalence. Pre-testing was done with Thai patients to refine the questionnaire. The validation study included 131 patients with LBP, who completed the Thai COMI-Back along with other validated questionnaires like the Oswestry Disability Index (ODI), and EQ-5D-5L. Reliability was assessed using Cronbach's alpha and intraclass correlation coefficients (ICC). Construct validity was determined by correlating COMI scores with those of reference scales.

resultsThe Thai COMI-Back exhibited strong reliability, with Cronbach's alpha values from 0.89 to 0.93 and ICC values over 0.80 for all domains. Construct validity was supported by significant correlations with reference scales, with Spearman's rho values ranging from 0.47 to 0.84. Floor and ceiling effects were acceptable for most items, with notable exceptions for symptom-specific well-being and work disability.

conclusionThe Thai COMI-Back shows strong psychometric properties, making it suitable for clinical and research use in Thailand.
