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

backgroundThe relationship between the duration of trigeminal neuralgia (TN) symptoms prior to initial microvascular decompression (MVD) and long-term outcomes is unclear. We evaluated whether the pre-operative symptom duration is associated with complete freedom from pain when MVD is performed as the initial procedure in TN secondary to arterial compression.

methodsPatients with purely paroxysmal TN who underwent MRI were retrospectively classified as cTN or iTN. Patients in each subtype of TN were categorized into pre-operative symptom duration groups of ≤ 24 months, 24-48 months, 48-72 months, or ≥ 72 months. Univariate and multivariate analyses were conducted for each subtype of TN. The first subgroup (i.e., ≤ 24 months) was treated as the reference subgroup for multivariate analysis.

resultsAt a median follow-up of 62.9 months (28.9-97.6 months), 15 (71.4%), 18 (100%), 12 (80.0%), and 13 (76.5%) MVDs for cTN with morphological changes resulted in pain freedom without medication in the ≤ 24, 24-48, 48-72, and ≥ 72 months symptom duration groups, respectively. At a median follow-up of 71.4 months (21.2-71.4 months), 8 (100%), 16 (94.1%), 10 (90.9%), and 8 (80.0%) MVDs for iTN morphological changes resulted in pain freedom without medication in the ≤ 24, 24-48, 48-72, and ≥ 72 months symptom duration groups, respectively. Multivariate analysis showed no difference in outcomes between groups. DISCUSSION: MVD performed later in the disease course is equally effective when compared to early MVD as the initial surgical procedure for the management of cTN with morphological changes and iTN without morphological changes.
