Prognostic role of neutrophil lymphocyte ratio and mean platelet volume in Bell's palsy: Comparison of diabetic and non-diabetic patients.
Observational study in Brazilian journal of otorhinolaryngology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
objectivesA low Neutrophil Lymphocyte Ratio (NLR) has been shown to be associated with good prognosis in Bell's Palsy (BP). However, the effect of chronic diseases that may affect the NLR, including Diabetes Mellitus (DM), has not been clarified in this context. This study aimed to evaluate the relationship between NLR and Mean Platelet Volume (MPV) in BP according to whether it is accompanied by DM, and their relationship with prognosis.
methodsA prospective observational study was conducted from May 2014 to May 2020 in a tertiary referral center, of all 79 consecutive participants diagnosed with BP in department of otolaryngology and 110 consecutive healthy participants admitted to the check-up unit. Patients diagnosed with BP were divided into two groups according to whether they were diagnosed with DM: diabetic BP patients (DM-BP, n = 33) and non-diabetic BP patients without any chronic disease (nonDM-BP, n = 46). Neutrophil (NEUT) and Lymphocyte (LYM) counts, and Mean Platelet Volume (MPV) were assessed from peripheral blood samples, and the NLR was calculated. Prognosis was evaluated using the House-Brackmann Score (HBS) six months after diagnosis.
resultsThe mean NLR was 2.85 ± 1.85 in BP patients and 1.69 ± 0.65 in the control group. The mean NLR was significantly higher in BP patients than healthy controls (p < 0.001). The mean NLR was 2.58 ± 1.83 in the nonDM-BP group, 3.23 ± 1.83 in the DM-BP group, and 1.69 ± 0.65 in the control group. The NLR was significantly higher in the nonDM-BP and DM-BP groups than in the control group (p < 0.05). The recovery was 90% according to the HBS. The optimal cut-off value was 2.41 (p = 0.5).
conclusionThe NLR was increased in both diabetic and non-diabetic BP and had similar prognostic value in predicting the HBS before treatment in diabetic and non-diabetic patients with BP. MPV wasn't significantly different in diabetic and non-diabetic BP patients compared with the normal population.
